描述:Phosphatidic Acid is produced by phospholipase D through the hydrolysis of phosphatidylcholine. The compound has been reported to activate the mitogen-activated protein kinase (MAPK) cascade, and interacts with Raf-1 by binding and mediating its translocation to the plasma membrane. Studies show that Phosphatidic Acid is an intracellular pH biosensor and couples metabolism to membrane biogenesis.
