Common Name | 19,20-DiHDPA |
---|
Description | 19,20-DiHDPA is one of the major metabolites produced when Docosahexaenoic acid (DHA) is incubated with NADPH-supplemented rat liver microsomes. Docosahexaenoic acid (DHA) is an essential fatty acid and the most abundant omega-3 fatty acid in neural tissues, especially in the retina and brain. DHA is also slowly metabolized by monkey seminal vesicles to 19,20-DiHDPA. The route of production likely proceeds through cytochrome P450-catalyzed epoxidation at the omega-3 double bond, followed by conversion to the vicinal diols by epoxide hydrolase. (PMID: 1742320 ). |
