This book provides a concise description of the metabolic pathways by which lipids of animal and plant membranes are formed. The book emphasizes modulation of these pathways by hormones, diet, environmental stress, and other factors. This new edition is extensively revised, containing new material on topics such as lipid-mediated signal transduction and lipid-induced protein translocation. The new edition also features an entirely new chapter on lipids covalently bound to proteins. The book is excellent for all researchers and students interested in membrane lipid metabolism.
