High density lipoprotein cholesterol

HDL is mainly synthesized in the liver, and its main physiological function is to transport phospholipids and cholesterol. High-density lipoprotein is an anti-atherosclerotic lipoprotein and a protective factor for coronary heart disease. Can promote the elimination of cholesterol in peripheral tissues and prevent the risk of atherosclerosis. High-density lipoprotein molecules carry cholesterol, which is an endogenous cholesterol ester that is transported backward. It is transported into the liver and then cleared from the blood. High-density lipoproteins take cholesterol from cell membranes, catalyzed by lecithin cholesterol acyltransferase to cholesterol esters, and then carry the cholesterol esters to very low-density lipoproteins and low-density lipoproteins. High-density lipoprotein contains 20% to 30% of total human cholesterol.
