1-Stearoyl-2-arachidonoyl-sn–glycerol is a diacylglycerol (DAG) with polyunsaturated fatty acid arachidonic acid and stearic acid in the sn-1 and sn-2 positions, respectively. 1-Stearoyl-2-arachidonoyl-sn–glycerol is a diacylglycerol is a potent activator of PKCα, PKCε, and PKCδ and also competitively binds to the Ras activator RasGRP. 1,2-Diacylglycerols are formed in cells through the hydrolysis of phosphatidylinositol 4,5-bisphosphate by Phospholipase C. DAGs activate Protein Kinase C (PKC), which is a key regulator of signal transduction, cellular regulation, and tumor promotion.
