Book excerpt: Abstract: Symposium proceedings of the Federation of Margarine Associations focused on lipids and lipoproteins. Structure and emergence of lipoproteins, and metabolic problems related to LDC and HDL are discussed. Alcohol's influence on lipoproteins and diabetes in clinical studies is reviewed along with biochemical studies, specifically corticosteriod biosynthesis and polyunsaturated fatty acids effects in heart muscle. Epidemiological papers, dietary studies, and fat processing technologies are examined. Extensive knowledge exists about lipoproteins and how apopolypeptides are attached to the phospholipids, cholesterol esters, triglycerides, and cholesterol as well as the amino acid sequence. Two areas for further research are suggested: a new apoprotein reported from studying the lymph, and the cellular functions and role of lipoproteins in triglyceride transport and specific organ activity.
