Book Description
The advances in lipid biochemistry over the past 25 to 30 years have been dramatic and exciting. The elucidation of the pathways of fatty acid biosynthesis and oxidation, the delineation of the biogenesis of cholesterol from small-molecular weight precursors, the structure proof of simple and complex lipids from plants, animals, and microorganisms, are excellent examples of the spectacular advances made during the golden era of lipid biochemistry. The multifaceted discoveries in these diverse areas of study could be attributed to development of highly sophisticated column chromatographic techniques for separation and purification of simple and complex lipids. The advent of thin-layer chromatography as well as gas liquid chromatography provided an explosive impetus to research developments in this field. Concomitant advances in mass spectrometry allowed an interface with gas-liquid chromatography which spawned even greater insight into the structure of lipids. These eventful days of lipid chemistry nearly 25 years ago led to a relatively quiescent period wherein scientists applied these newly available techniques to investigation of the behavior of isolated (lipid) enzyme systems and to unraveling the intricacies of the metabolic behavior of lipids in the intact cell or whole organisms. Then, in the early 1960s, a decided change in research emphasis developed with the advent of a simple, reproducible procedure for the isolation of cell membranes.

Book Description
This book has a pedigree. It has developed from earlier publications by the author and from his experience over 50 years in reading, writing, thinking, and working with lipids and fatty acids. The earlier publications are: (i) An Introduction to the Chemistry of Fats and Fatty Acids, Chapman and Hall, 1958. (ii) An Introduction to the Chemistry and Biochemistry of Fatty Acids and their Glycerides, Chapman and Hall, 1967. (iii) Lipids in Foods: Chemistry, Biochemistry, and Technology (with F. A. Norris), Pergamon Press, 1983. (iv) The Lipid Handbook (with J. L. Harwood and F. B. Padley), Chapman and Hall, first edition 1986, second edition 1994. (v) A Lipid Glossary (with B. G. Herslof), The Oily Press, Dundee, 1992. (vi) Lecture notes for a course on Fatty Acids and Lipids designed for those entering the oil and fat industry and given on over 20 occasions since 1977. The book is dedicated to the next generation of lipid scientists. The study of lipids now involves many disciplines, all of which require a basic knowledge of the chemical nature and properties of these molecules, which is what this book is about. It is written particularly for those who, with some knowledge of chemistry or biochemistry, need to know more about the nature of lipids and fatty acids.

Book Description
Lipid Metabolism focuses on the regulation and metabolism of lipids. This book is composed of 10 chapters that specifically deal with fatty acids, prostaglandins, glycerides, glycerophosphates, cholesterol, isoprenoids, and aromatic compounds. This text starts with an overview of fatty acid metabolism and its controlling factors. This topic is followed by discussions on the physiochemical aspects of oxidative metabolism of fatty acids, with a special emphasis on the role of carnitine in this process. A chapter highlights the several important aspects of higher plant lipid metabolism. Other chapters are devoted to the structures, biosynthesis, and metabolism of prostaglandins, bacterial lipids, phospholipids, glycerides, and steroids. The final chapters describe the biogenesis of aromatic substances through the polyketide path, including polyisoprenoid quinines and related compounds.

Book Description
The Chemistry and Technology of Edible Oils and Fats contains the proceedings of a conference arranged by Unilever Limited and held at Port Sunlight in England on March 10-12, 1959. The papers explore the chemistry and technology of edible oils and fats, with emphasis on analytical procedures, the methods of industrial processing, and the pattern of dietary fat consumption seen from the viewpoint of the economist. This book is comprised of seven chapters and opens with a discussion on the physical and chemical properties of the constituents of edible oils and fats, with particular reference to the fatty acids, the glycerides, and those closely related compounds which are fatty in a general sense. The following chapters focus on the pattern of fatty food consumption in the United Kingdom; the methods used for the analysis of oils and fats; processing of oils and fats for edible purposes; the use of the isotopic dilution technique in the determination of linoleic acid; and the application of gas/liquid chromatography to the analysis of atheromatous plaques. The final chapter deals with the use of spectroscopic and X-ray techniques in the analysis of oils and fats. This monograph will be a useful resource for chemists and food technologists.

Book Description
The hydroxamic acid reaction conditions for the determination of esterified fatty acids were modified to the extent that the variable factors involved were controlled so that the molar absorptivities per ester group for triglycerides, cholesteryl esters of long-chain fatty acids, and phosphatides were equivalent through 8 microequivalent ester. The amount of water present during the formation of hydroxamates was the most important single factor in obtaining equivalent color values with these 3 types of esters. The accuracy and precision of the method were well defined by showing that the optical density values for 5 different ester standards were on the identical straight line curve. Spectral curves between the wavelengths of 410 and 700 millimicron with standard carboxylic acid esters and Folch extracts of rat serum, rat liver, and human serum were qualitatively and quantitatively identical. A long chain cholesteryl ester must be used as one of the standard esters because of its solubility characteristics and water sensitivity. Cholesteryl acetate can not be used as a reliable representative in place of a long chain cholesteryl ester. (Author).
