| Description | 11,12,15-trihydroxyeicosatrienoic acid (11,12,15-THETA) is a metabolite of the 15-lipoxygenase (15-LO) pathway of arachidonic acid (AA). 11,12,15-THETA is an endothelium-derived relaxing factor. Acetylcholine stimulates AA release from membrane phospholipids of vascular endothelial cells (ECs). AA is released from phosphatidylcholine (PC) and phosphatidylethanolamine (PE) by phospholipase A2 (PLA2), or from phosphatidylinositol (PI) by phospholipase C (PLC) pathway. The diacylglycerol (DAG) lipase can convert DAG into 2-arachidonoylglycerol from which free AA can be released by monoacylglycerol (MAG) lipase or fatty acid amidohydrolase (FAAH). 11,12,15-THETA mediates the acetylcholine-induced vaso-relaxation, via activation of the K+ channels to hyperpolarize the smooth muscle membrane and induce relaxation.
