Triolein (glyceryl trioleate) 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.[1]

Triolein is also known as glyceryl trioleate and is one of the two components of Lorenzo's oil.[2]

The oxidation of triolein is according to the formula:

C
57H
104O
6 + 80 O
2 → 57 CO
2 + 52 H
2O

This gives a respiratory quotient of or 0.7125. The heat of combustion is 8,389 kcal (35,100 kJ) per mole or 9.474 kcal (39.64 kJ) per gram. Per mole of oxygen it is 104.9 kcal (439 kJ).
