1 HGS Polyhedron Molecular Model

Prominent features

The use of 14- 20- 26- and 32-hedra made of ABS resin as atoms is the most prominent feature of these models By using these polyhedra various bond angles needed for the molecular models can be precisely represented and since the polyhedra have various symmetry factors by appropriately assembling them the symmetrical characters of molecular models and crystal models can be easily realized Connecting bonds are made of polyacetal sticks or aluminium tubes both being light in weight and sufficiently strong Setting of the bonds is designed so as to permit the bond length of the molecular models to be precisely observed As the bonds are made of strong flexible plastics the models of even complicated molecules can be easily assembled Also this feature makes possible the easy assembly of models of strained compounds and distorted crystals

Another advantageous feature of these HGS models is the variety of atom-polyhedra available In sets intended mainly for individual use the polyhedral are supplied in small sizes while in those for lecture use they are in large sizes (Fig 1) They are also in different colors to indicate different elements More-over as mentioned above three different shapes of polyhe-dron are contained in each set These are as follows

A 14-hedron results from truncating the eight corners of a cube along the lines passing through the center of each edge as shown in Fig2 A This is the basic atom-polyhedron and is called the sp3 type with 4 holes or the d2sp3 type with 6 holes

The 20-hedron shown in Fig2 B is called the sp2 type and is used as a component of the benzene ring An sp2 type 20-hedron with holes also at the top and bottom is called the dsp3 type

The 26-hedron is made by truncating all the corners of the 14-hedron (Fig 2 C )

The 32-hedron is made also by truncating all the corners of pentagonal dodecahedron including both faces of pentagonal dodecahedron and icosahedron (Fig2 D )

The angles represented in these various polyhedra are shown in Fig3

HGS Polyhedron Molecular Model has been developed under the direction of Dr Kazuo Hata Emeritus Professor of Tokyo Metropolitan University and Dr Masayoshi Nakahara Professor of Rikkyo (St Paul) University

Connection of ldquobondrdquo to ldquoatomrdquo and the bond length

For connecting the bonds to atom-polyhedra three modes are devised according to different combinations as shown in Fig4 The connection between an atom and its σ-bond is designed so as to rotate freely around the σ-bond but with some tightness This somewhat tight rotation around the bonds is

useful for the observation of conformational changesThe bond length in assembled models can be precisely repre-sented by the length shown in Fig5 and can be measured by using the Aring unit scale provided

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and

1 HGS Polyhedron Molecular Model

Prominent features

The use of 14- 20- 26- and 32-hedra made of ABS resin as atoms is the most prominent feature of these models By using these polyhedra various bond angles needed for the molecular models can be precisely represented and since the polyhedra have various symmetry factors by appropriately assembling them the symmetrical characters of molecular models and crystal models can be easily realized Connecting bonds are made of polyacetal sticks or aluminium tubes both being light in weight and sufficiently strong Setting of the bonds is designed so as to permit the bond length of the molecular models to be precisely observed As the bonds are made of strong flexible plastics the models of even complicated molecules can be easily assembled Also this feature makes possible the easy assembly of models of strained compounds and distorted crystals

Another advantageous feature of these HGS models is the variety of atom-polyhedra available In sets intended mainly for individual use the polyhedral are supplied in small sizes while in those for lecture use they are in large sizes (Fig 1) They are also in different colors to indicate different elements More-over as mentioned above three different shapes of polyhe-dron are contained in each set These are as follows

A 14-hedron results from truncating the eight corners of a cube along the lines passing through the center of each edge as shown in Fig2 A This is the basic atom-polyhedron and is called the sp3 type with 4 holes or the d2sp3 type with 6 holes

The 20-hedron shown in Fig2 B is called the sp2 type and is used as a component of the benzene ring An sp2 type 20-hedron with holes also at the top and bottom is called the dsp3 type

The 26-hedron is made by truncating all the corners of the 14-hedron (Fig 2 C )

The 32-hedron is made also by truncating all the corners of pentagonal dodecahedron including both faces of pentagonal dodecahedron and icosahedron (Fig2 D )

The angles represented in these various polyhedra are shown in Fig3

HGS Polyhedron Molecular Model has been developed under the direction of Dr Kazuo Hata Emeritus Professor of Tokyo Metropolitan University and Dr Masayoshi Nakahara Professor of Rikkyo (St Paul) University

Connection of ldquobondrdquo to ldquoatomrdquo and the bond length

For connecting the bonds to atom-polyhedra three modes are devised according to different combinations as shown in Fig4 The connection between an atom and its σ-bond is designed so as to rotate freely around the σ-bond but with some tightness This somewhat tight rotation around the bonds is

useful for the observation of conformational changesThe bond length in assembled models can be precisely repre-sented by the length shown in Fig5 and can be measured by using the Aring unit scale provided

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and

1 HGS Polyhedron Molecular Model

Prominent features

The use of 14- 20- 26- and 32-hedra made of ABS resin as atoms is the most prominent feature of these models By using these polyhedra various bond angles needed for the molecular models can be precisely represented and since the polyhedra have various symmetry factors by appropriately assembling them the symmetrical characters of molecular models and crystal models can be easily realized Connecting bonds are made of polyacetal sticks or aluminium tubes both being light in weight and sufficiently strong Setting of the bonds is designed so as to permit the bond length of the molecular models to be precisely observed As the bonds are made of strong flexible plastics the models of even complicated molecules can be easily assembled Also this feature makes possible the easy assembly of models of strained compounds and distorted crystals

Another advantageous feature of these HGS models is the variety of atom-polyhedra available In sets intended mainly for individual use the polyhedral are supplied in small sizes while in those for lecture use they are in large sizes (Fig 1) They are also in different colors to indicate different elements More-over as mentioned above three different shapes of polyhe-dron are contained in each set These are as follows

A 14-hedron results from truncating the eight corners of a cube along the lines passing through the center of each edge as shown in Fig2 A This is the basic atom-polyhedron and is called the sp3 type with 4 holes or the d2sp3 type with 6 holes

The 20-hedron shown in Fig2 B is called the sp2 type and is used as a component of the benzene ring An sp2 type 20-hedron with holes also at the top and bottom is called the dsp3 type

The 26-hedron is made by truncating all the corners of the 14-hedron (Fig 2 C )

The 32-hedron is made also by truncating all the corners of pentagonal dodecahedron including both faces of pentagonal dodecahedron and icosahedron (Fig2 D )

The angles represented in these various polyhedra are shown in Fig3

HGS Polyhedron Molecular Model has been developed under the direction of Dr Kazuo Hata Emeritus Professor of Tokyo Metropolitan University and Dr Masayoshi Nakahara Professor of Rikkyo (St Paul) University

Connection of ldquobondrdquo to ldquoatomrdquo and the bond length

For connecting the bonds to atom-polyhedra three modes are devised according to different combinations as shown in Fig4 The connection between an atom and its σ-bond is designed so as to rotate freely around the σ-bond but with some tightness This somewhat tight rotation around the bonds is

useful for the observation of conformational changesThe bond length in assembled models can be precisely repre-sented by the length shown in Fig5 and can be measured by using the Aring unit scale provided

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and

Connection of ldquobondrdquo to ldquoatomrdquo and the bond length

For connecting the bonds to atom-polyhedra three modes are devised according to different combinations as shown in Fig4 The connection between an atom and its σ-bond is designed so as to rotate freely around the σ-bond but with some tightness This somewhat tight rotation around the bonds is

useful for the observation of conformational changesThe bond length in assembled models can be precisely repre-sented by the length shown in Fig5 and can be measured by using the Aring unit scale provided

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

Professor of Keio University and Dr Koujiro Iso Professor of University of Tokyo

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

HGS Biochemistry Molecular Model

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

Professor of Keio University and Dr Koujiro Iso Professor of University of Tokyo

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 Double Bond and Aromatic sp2 Atoms

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

2 HGS Space-Filling Molecular Model

FeaturesThe models combine the idea of both ball-and-stick and space-filling models allowing one to visualize not only molecular frameworks but also molecular structures covered with electron clouds

A Transparent except -marked pieces belowB Opaque

Materials and Parts

Scale

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

21

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

( For reference)

HGS Space-Filling Molecular Model

Properly used materials polyacetal for bonding and ABS and polyacrylate for covering make the model durable yet flexible It is also light weight and even a large molecule can be constructed easily Bonds fit snugly and firmly but can be easily disassembled Conformational changes are easily attainable Parts are beautifully color coded

The scale 1 Aring = 10 cm not only makes this molecular model quite handy but also extremely versatile to be used interchangeably with the ldquoHGS Biochemistry Molecular Modelrdquo

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

HGS Biochemistry Molecular Model

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

Professor of Keio University and Dr Koujiro Iso Professor of University of Tokyo

Sphere Size of Space-Filling Atomic Models

In space-filling molecular models each atom is assigned a spherical volume representing its electron cloud the size of which is defined by its van der Waals radius The data of van der Waals radii were first reported by L Pauling (1939) and then revised by A Bondi (1964)

Most atoms in HGS space-filling models are assigned sphere sizes that are smaller than the van der Walls radii For example the size of S-1 sp3-Carbon is 120 Aring which is 71 of the van der Waals radius of 170 Aring However bond radii and angles remain unchanged Other common atoms are S-14-1 Hydrogen (size 100 Aring 83) S-2 sp3-Nitrogen (size 120Aring 77) S-12-1 single bond Oxygen (size 135 Aring 89) etc The reduced spheres serve to facilitate the construction of molecules 100 size atoms would be difficult to use because of tightness between adjacent atoms

When using atoms with reduced spheres one can easily construct organic molecules For example it is easy to assemble methylcyclohexane (see Figure) and the model shows the space-filled molecular shape

Another advantage of reduced spheres in space filling models is the ability to show conformational changes such as cyclohexane ring inversion where an equatorial methyl group moves to the axial position and vice versa In such a case it is better to use model A (transparent) than model B (opaque) because one can see the chair form of the cylclohexane frame inside the electron cloud as well as the inverted chair conformation

HGS space filling models offer ldquo100 sizerdquo atoms for certain elements including P S Cl and others These are useful for constructing hetero-compounds or halogen compounds

For sp 2-Carbon atoms two types are available that differ in sphere size S-5-1 (170Aring 100) and S-5-2 (125 Aring 74) but the bond radii and angles remain unchanged The tall ldquo100 sizerdquo atom S-5-1 emphasizes the bulkiness of π-electrons compared to the S-5-2 sp 2-C atom For the latter atom parts S-27 and S-28 are useful to express π-MOs So one can choose these atoms depending on the intended purpose of the model

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 Double Bond and Aromatic sp2 Atoms

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 Double Bond and Aromatic sp2 Atoms

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

4 HGS Stereochemistry Molecular Model

Features

As seen in the above figures the HGS Stereochemistry Molecular Models are suited for constructing molecular skeletons the scale of the model being 1 Aring = 20 cm It is thus very useful for configurational and conformational studies of organic inorganic and biochemical molecules The chair boat or envelope inversions of ring structures can be readily performed strained rings can be constructed without difficulty and interatomic distance and torsion angle can be measured directly Particularly the data are important for the analyses of NMR NOE coupling constants CD (circular dichroism) exciton chirality etc Thus these models are well-suited for stereochemical assignments and discussionsMaruzen provides the recently updated 4000A Standard Set and 7000A Advanced Set Both contain sufficient carbon atoms heteroatoms and three-membered ring units for constructing large and complex molecules For example the largest set 7000A contains 112 sp3-C atoms 92 sp2-C atoms H atoms for H-bond double bond O atoms for H-bond halogen atoms sp3-Si atoms sp3-P atoms sp3-S atoms octahedral metal atoms (bond length 120 Aring and 140 Aring) cyclopropane aziridine epoxide etc Thus a wide variety of organic inorganic and biochemical molecules can be constructed by these kits For individual students there is a compact 4010 setThe 4000A set and 7000A set are therefore indispensable for stereochemical research and discussions with 3D visualization

Recommendation by Professor Nobuyuki Harada (Tohoku University Sendai Japan) Professor Nina Berova (Columbia University New York) and Professor Koji Nakanishi (Columbia University New York)

It is featherlight slim and flexible and yet quite durable-ideal not only for research chemists but also for learning students as well New scale 1 Å = 2 cm offers an easy handling and assures the precise estimation of interatomic distances Conformational changes can be attained easily and smoothly Yet any specific conformer can be fixed without any special aid The flexible nature of bonding allows ones to construct four-and five-membered rings using usual units The model is suitable in the fields of organic chemistry biochemistry and inorganic chemistry both for educational and research purposes

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

2 Double Bond and Aromatic sp2 Atoms

A planar sp2 atom has three bonds with an angle of 120deg as shown in Shape where one bond has a stick while the remaining two have holes

It is easy to construct a benzene ring by connecting six ORG-5 sp2 Carbon atoms

The C=C double bond is similarly assembled by connecting two ORG-5 sp2 Carbon atoms as exemplified in Fig 2 The part ORG-21 double bond lock is useful for preventing the rotation around the double bond fit the nub of a bond in the pocket of a double bond lock (Fig 2)

The single bond Oxygen atom with angle 120deg is necessary for constructing phosphate groups or hydrogen bonding between purine and pyrimidine bases (Fig 4) To make this atom part cut one hole-bond of ORG-7 Oxygen atom with nippers or wire cutters

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

1 Tetrahedral sp3 Atoms

A regular tetrahedral sp3 atom has four bonds with the bond angle of 109deg28rsquo as shown in the accompanying Table under the column heading ldquoShaperdquo Here two bonds have sticks while the other two have holes It is easy therefore to connect atoms as exempli-fied in Fig 1 If necessary the ORG-20 Connector is useful for connecting two hole-bonds as shown for methane (Fig 1)

The bond radius of each atom is listed in the Table

Conformational changes accompany the rotations abound single bonds If a bond in the model is tight and difficult to rotate sewing machine oil will facilitate smooth rotation The model parts are resistant to such oil

HGS Biochemistry Molecular Model

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

Professor of Keio University and Dr Koujiro Iso Professor of University of Tokyo

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

HGS Biochemistry Molecular Model

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

1 Aring = 10 cm

HGS Biochemistry Molecular Model has been developed under the direction of Dr Itaru Watanabe

Professor of Keio University and Dr Koujiro Iso Professor of University of Tokyo

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

1 Aring = 10 cm

It is easily assembled and accurate Important biochemical groups are assembled into units such as peptide bonding units ribose and deoxyribose ring units etc These groups are designed for the easy addition of other parts and units

As a general rule the center of atoms is indicated by small spheres The various parts are color-coded to aid identification Each of the models is colored to conform with international practice

Made of polyacetal resin light weight and strong they remain in good condition for long use

Special attention and precision processing have been given to the joints so that they can be assembled easily without a supporting stand But to construct large models like DNA tRNA proteins and enzymes a standing frame or supporter for polypeptides and polynueleotides are available for display

A part of DNA-Z form

Deoxyribonucleic acid (DNA) represents a very important class of biopolymers carrying the genetic information of living things In 1953 J Watson and F Crick proposed the double helix structure of B-DNA based on X-ray diffraction data Maruzen-HGS provides exact DNA models assembled with the biochemistry molecular model set The models are highly detailed and suited for undergradu-ate and graduate students to study genetics The more simplified B-DNA models DNA-10 and DNA-15 are now available as shown here The A-T and G-C base pairs are represented with plates while sugar and phosphate groups are made with platespolyhedron atoms DNA-10 and DNA-15 models have 10 and 15 base pairs respectively and
