Triglyceride
A triglyceride /traiGLIseraid/ is a type of ester that comes from glycerol and three fatty acids.[1] Triglycerides are a type of lipid found in the blood. They help enable the movement of adipose fat and glucose from the liver. Triglycerides are the main molecules that make up vegetable oil and animal fats.[2] They are also a major component of oils found on human skin (sebum).[3] Too much triglycerides has been linked to a number of cardiovascular diseases.[4]

Example of an unsaturated fat triglyceride (C55H98O6). Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid.
Example of a natural mixed triglyceride with residues of three different fatty acids. The first fatty acid residue is saturated (blue highlighted), the second fatty acid residue contains one double bond within the carbon chain (green highlighted).
