Metabolite Identification
Common Name9(10)-EpODE
Description9(10)-EpODE is an epoxy fatty acid where linolenic acid has been epoxidized at the 9-10 positions through the action of cytochrome P450 epoxygenases. Epoxy fatty acids are termed 'leukotoxins' (the term includes a range of diverse compounds), because they produce their primary toxic effects against leukocytes. At high dosages, they have toxic cardiovascular effects, which can even result in death.
