Metabolic pathways of anandamide. Anandamide (AEA) can be metabolized by 1) fatty acyl amide hydrolase (FAAH) to release free arachidonic acid and ethanolamine, 2) 12- or 15-lipoxygenases to form 12(S)-hydroxyeicosatetraenoic acid-ethanolamine (HETE)-EA and 15(S)-HETE-EA and other HETEs, 3) by cytochrome P450s to form HETE-EAs and EET-EAs, and 4) by cyclooxygenase-2 (COX-2) to form prostamide E2 and other prostamides.
