What are triglycerides?
Triglycerides are the chemical form in which most fat exists in food as well as in the body. They're also present in blood plasma and, in association with cholesterol, form the plasma lipids.
Lipids are oily compounds that are insoluble in water and comprise the structural material in living cells. Cholesterol and triglycerides are examples of lipids. Since these lipids are insoluble, they form complexes known as lipoproteins. A lipoprotein is a round particle that has either certain types of cholesterol or triglycerides at its center. Towards the surface, it consists of other lipids along with proteins.
Triglycerides enter the body in two ways.:
Triglycerides that are not immediately used by the body are, along with additional triglycerides that are synthesized by the liver, repackaged as VLDL (very low density lipoprotein) cholesterol and released into the blood by the liver.
