Triglycerides are also lipids, just like cholesterol, which are composed of glycerol and fatty acid molecules and stored in the fatty tissues of your body. These lipids are made in the small intestine, from fats brought in through food and during the metabolism of fast sugars by the liver. They are normally present in the body and are an important source of energy for your body.
High levels of triglycerides in the blood are a risk marker for cardiovascular disease.
