The chapters presented here provide the reader with an awareness of the divergent views of what constitutes racism and frameworks for reducing it. This book points out that the dialogue and research on this subject since the mid-1970s have yielded increased contro versy over the theories, foundation, and continued existence of racism. Ironically, what we viewed in the 1954Brown decision and the Civil Rights Act of 1964as the beginning of the end of racism turned out to be the beginning of confusion over the course of action to ensure societal acceptance of political mandates. Hence, the title...

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...

Interest in and emphasis upon different aspects of the sphingolipids have, in general, followed the biochemical developments of the day. The early inves- tigators were preoccupied principally with the isolation of "pure" compounds and structural elucidation. This historical perspective is found in the discus- sion presented in Chapter 1 (Section 1. 1. 2 and Table III). Still, the isolation and structural characterization of glycolipids are the basic foundation of all our knowledge of enzymology, immunology, and cell biology. Recent infor- mation obtained on structure has greatly affected the...

The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function...

Phospholipases are a class of ubiquitous enzymes that have in common their substrate and the fact that they are all esterases. Beyond that, they are a diverse group of enzymes that fall into two broad categories, the acyl hydro lases and the phosphodiesterases. The former group is made up of the phos pholipases Al and A, phospholipase B, and the lysophospholipases. On the 2 other hand, the phosphodiesterases are the phospholipases C and D. The scheme indicates the site of attack of each type of phospholipase. PLA 1 PLB j ft 0 -C-O-C-R d 2 I 1 R-C-0-C-H 0 2 /H2-6-0-U-0-x PLA, 6- '" PLC PLD The...

The early history and development of the field of glycolipids was concerned mainly with the predominant glycolipids found in higher animal tissues, namely the glycosphingolipids, as has been extensively documented by J. N. Kanfer and S. Hakomori in Volume 3 of this series. The major glycolipids in organisms of the plant kingdom, however, such as bacteria, yeasts and fungi, algae, and higher plants, are glycoglycerolipids, although glycosphingolipids are also present as minor components in these organisms, except for bacteria. It is of interest that one of the pioneers in glycosphingolipid...
