Triacylglycerol is the most abundant lipid in the body, consisting of 3 molecules of fatty acids and 1 molecule of glycerol esterified, and is the main source of energy in the body. Triacylglycerols come from the breakdown of fats in food, and the liver also converts certain sugars in the blood into triacylglycerols. If triacylglycerols are in excess, they can make the body obese and cause atherosclerosis and fatty liver. Increased triacylglycerol is closely related to atherosclerotic cardiovascular disease and is one of the important risk factors for cardiovascular disease. When the serum triglyceride level is elevated and combined with atherosclerosis, drug therapy should be used. In terms of drug selection, fibrates, such as benzafibrate and fenofibrate, as well as niacin, can be used.
