Triglycerides are the main type of fat found in the body and in foods. They are also called triacylglycerols. A triglyceride molecule is made up of glycerol and three fatty acids. Glycerol is a simple alcohol, and fatty acids are long chains of carbon atoms bonded to hydrogen atoms, with an acid group at one end. The type of fatty acids attached to the glycerol determines whether the triglyceride is saturated or unsaturated.

Triglycerides are the primary form of stored energy in the body. When you eat more calories than you need, your body converts the excess into triglycerides, which are then stored in fat cells. When your body needs energy between meals or during exercise, it breaks down these stored triglycerides. In the diet, triglycerides are found in oils, butter, lard, and fatty meats. They are a source of calories and essential fatty acids. High levels of triglycerides in the blood, known as hypertriglyceridemia, can be a risk factor for heart disease. Lifestyle factors such as diet, exercise, and weight management can influence triglyceride levels.
