BIOCHEMISTRY OF THE FATTY ACIDS audi T h e i r C o m p o u n d s , t h e Lipids

by W. R. Bloor Professor of Chemistry and Pharmacology 9 Uni-versity of Rochester

AnaeAiccut ChetniccU Society MosiofAafJt Ala. 93 This -volume presents a n exhaustive critical review of the chemistry and functions o f the important group of substances included in the term "fatty acids." T h e part played by fats and lipids in the complicated mechanism of digestion and nutrition, as well as in the blood and tissues, i s discussed in great detail. The relation of fatty acid metabolism t o such pertinent subjects as vitamins, enzymes, the reproductive cycle, embolism, anemia, cancer, dia­betes, syphilis, arthritis, and others, is emphasized. In short, this book pro­vides a much-needed study of a group of organic compounds, the fats, so closely associated in the human body with carbohydrates and proteins. It will b e of t h e greatest value to physicians, nutritionists, organic chemists, and biochemists, as "well as in food and pharmaceutical fields. A complete bibli­ography is given for every chapter. CONTENTS: Chemistry: Descriptive and Analytical.

as to category and availability in the letter. Certain exceptions were noted; The resMctiona are not intended to apply to

existing subcontract relationships, particularly for production of difficult or complicated items, where their application might tend to delay or interfere with production. The restrictions do not apply to placing of subcontracts with firm which currently employ less than 100 wage earn­ers and which will not employ more than 100 wage earners during the performance of the sub­contracts.

However in applying these restrictions to future subcontracts placed under a prime contract, you will not be expected, once you have set up your subcontracting plans, to grve effect to changes in the classification of labor supply areas after the execution of the prime contract, where to do so would decrease the efficiency of your subcon­tracting.
