Plasma lipids, triglyceride/fatty acid pattern, and plasma insulin in fasted healthy volunteers during continuous ingestion of ethanol: Influence of lipolysis inhibited by Nicotinic Acid

Abstract Healthy fasted volunteers were subjected to an acute oral ethanol load over 12 h after a diet of 3 days with high linolenic acid content. Free fatty acids, triglycerides, glycerol, phospholipids, cholesterol and insulin, as well as the fatty acid pattern of triglycerides in the plasma, were determined during the test. The test was repeated with nicotinic acid added. The lipid values obtained and the comparisons of fatty acid composition both indicate the predominant role of peripheral lipolysis in the genesis of acute ethanol-induced hypertriglyceridemia, in spite of the possibility of enhanced synthesis of palmitic acid in the liver.
