Triolein is a symmetrical triglyceride derived from glycerol and three units of the unsaturated fatty acid oleic acid. Most triglycerides are unsymmetrical, being derived from mixtures of fatty acids. Triolein represents 4–30% of olive oil. Triolein is also known as glyceryl trioleate and is one of the two components of Lorenzo's oil. The oxidation of triolein is according to the formula: + 80 → 57 + 52 This gives a respiratory quotient of or 0.7125. The heat of combustion is per mole or per gram. Per mole of oxygen it is .
