• Sommario/riassunto: Since the publication of the first edition of this successful and popular book in 1970, the subject of lipid biochemistry has evolved greatly and this fifth up-to-date and comprehensive edition includes much new and exciting information. Lipid Biochemistry, fifth edition has been largely re-written in a user-friendly way, with chapters containing special interest topic boxes, summary points and lists of suggested reading, further enhancing the accessibility and readability of this excellent text. Contents include abbreviations and definitions used in the study of lipids, ro
