Description | 9,10-Epoxyoctadecanoic acid, also known as 9,10-epoxystearate or 8-(3-octyloxiran-2-yl)octanoate, belongs to the class of organic compounds known as lineolic acids and derivatives. These are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. 9,10-Epoxyoctadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 9,10-Epoxyoctadecanoic acid is an epoxy fatty acid. Outside of the human body, 9,10-epoxyoctadecanoic acid has been detected, but not quantified in, several different foods, such as celery stalks, hedge mustards, roselles, brussel sprouts, and pepper (spice). 9r,10s-epoxy-stearic acid is found in Jodina rhombifolia and Shorea robusta. 9r,10s-epoxy-stearic acid was first documented in 1995 (PMID: 8520208). This could make 9,10-epoxyoctadecanoic acid a potential biomarker for the consumption of these foods (PMID: 19120447) (PMID: 12505783). |
