1-Oleoyl lysophosphatidic acid

1-Oleoyl lysophosphatidic acid is a species of lysophosphatidic acid (LPA) containing oleic acid at the sn-1 position. Phosphatidic acid is made either through a two step process involving liberation of diacylglycerol (DAG) by phospholipase C (PLC) follow by phosphorylation of DAG by diglycerol kinase or directly through the action of phospholipase D (PLD). Hydrolysis of the fatty acid at the sn-2 position by phospholipase A2 (PLA2) yields bioactive LPA, which binds to one of five different G protein linked receptors to mediate a variety of biological responses including platelet aggregation, cell proliferation, smooth muscle contraction, cell motility and neurite retraction. 1-Oleoyl lysophosphatidic acid is the most potent of the LPA analogs for calcium mobilization in A431 cells and for growth stimulation of a variety of cell lines.
