Description |
1-<wbr />Stearoyl-<wbr />2-<wbr />arachidonoyl-<wbr /><em>sn</em>-<wbr />glycerol is a diacylglycerol (DAG) with polyunsaturated fatty acid arachidonic acid and stearic acid in the sn-1 and sn-<wbr />2 positions, respectively. 1-<wbr />Stearoyl-<wbr />2-<wbr />arachidonoyl-<wbr /><em>sn</em>-<wbr />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. <h4><strong>References</strong></h4> 1) Lapetina, E.G., Reep, B., Ganong, B.R. & Bell, R.M., (1985), <a href="https://www.ncbi.nlm.nih.gov/pubmed/3155733">Exogenous sn-1, 2-diacylglycerols Containing Saturated Fatty Acids Functions as Bioregulators of Protein Kinase C in Human Platelets</a>", <em>J.
