OriginDerived from glycerol and oleic acid, a monounsaturated fatty acid typically sourced from plant oils. Synthesized through esterification of glycerol with oleic acid under controlled temperature and catalyst conditions.
Triolein is a triglyceride formed by esterification of the three hydroxy groups of glycerol with oleic acid. Triolein is one of the two components of Lorenzo's oil. It has a role as a plant metabolite and a Caenorhabditis elegans metabolite. It is functionally related to an oleic acid.
