General description

Phosphatidic acid (PA) is synthesized by the action of phospholipase D (PLD) on glycerophospholipids and by phosphorylation of diacylglycerol (DAG) by DAG kinase.


Egg PA has been used in SEIPEN binding studies. It is suitable for use in the preparation of liposomes and to deduce different species of phosphatidic acid from egg by liquid chromatography-mass spectroscopy (LC-MS) and least squares spectral resolution (LSSR) analysis.

Biochem/physiol Actions

Phosphatidic acid (PA) contributes to membrane biogenesis by involving in the synthesis of glycerophospholipids like phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylserine. PA is implicated in cell signaling.
