Description | Cholesteryl eicosapentaenoic acid is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues, and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides). In patients with triglyceride levels above 500 mg/dl, approximately 4 g/day of eicosapentaenoic acid reduces triglyceride levels 45% and very low-density lipoprotein cholesterol levels by more than 50%. Physical exercise and fish oil (a rich source of eicosapentaenoic acid) suppress the activity of endothelial lipase (EL) and this, in turn, enhances the plasma concentrations of HDL cholesterol. EL has been shown to have a significant role in modulating the concentrations of plasma HDL. (PMID: 17461707 , 15664301 , 15524182 , 15485592 ). |
