Description

Ether Lipids: Biochemical and Biomedical Aspects is a 21-chapter text that explores the procedures for the analysis, synthesis, and biomedical application of ether lipids. This book surveys first the chromatographic analysis of ether lipids and their characterization by mass spectrometry. The following chapter describes the chemical synthesis of lipids containing alkyl or 1-alkenyl chains. Three chapters are devoted to the biosynthesis of ether lipids, and four others cover unusual ether lipids. Significant chapters focus on biologically active ether lipids, including the naturally occurring platelet-activating factor and synthetic alkyl analogs of lysophosphatidylcholines, which exhibit cancerostatic properties. This text further discusses the application of these and related substances in biomedical research as well as in clinical diagnosis and therapy. The remaining chapters highlight the use of ether lipids in studies aimed at elucidating the structure of membranes and their functions. Organic chemists, biochemists, and researchers in the biomedical field will find this book invaluable.
