1-Oleoyl-2-hydroxy-sn-glycero-3-PA is a species of LPA containing oleic acid at the sn-1 position. Phosphatidic acid is produced either directly through the action of PLD or through a two step process involving liberation of DAG by PLC followed by phosphorylation of DAG by diglycerol kinase.{2656} Hydrolysis of the fatty acid at the sn-2 position by PLA2 yields bioactive LPA. LPA binds to one of four different G-protein linked receptors{13001} to mediate a variety of biological responses including cell proliferation, smooth muscle contraction, platelet aggregation, neurite retraction, and cell motility.{2656} 1-Oleoyl-2-hydroxy-sn-glycero-3-PA is the most potent of the LPA analogs for calcium mobilization in A431 cells{2665} and for growth stimulation of a variety of cell lines.{2666}
