8,11,14-Eicosatrienoic acid, also known as dihomo-γ-linolenic acid , is a polyunsaturated fatty acid (PUFA) produced from γ-linolenic acid by the action of fatty acid elongases. It can be metabolized by the cyclooxygenase pathway to produce 1-series prostaglandins (PGs) (e.g., PGE1). (±)14(15)-EpEDE is an EpEDE acid formed from 8,11,14-eicosatrienoic acid. This monoepoxide can be generated from the PUFA, in vitro, by the action of a strong oxidizing agent. Alternatively, this compound may be produced, in vivo, by epoxidation of the PUFA by cytochrome P450 epoxygenases. The biological properties of this compound are poorly understood.
