Advances in Lipid Research, Volume 13 is a four-chapter text that emphasizes the biological aspects of lipoproteins. The first chapter reviews the status of lipoprotein metabolism, specifically the functional, structural, and metabolic interrelationships of lipoproteins. The second chapter covers aspects of lipid metabolism in diabetes and the stresses that can cause alterations in carbohydrate metabolism. The third chapter discusses the developments in understanding the physicochemical basis of gallstone formation. The fourth chapter deals with the biosynthesis and composition of milk fat. This chapter also presents a summary of some of the important features of milk fat production processes. This book will prove useful to lipid chemists, biochemists, physicians, and researchers.
