General description

Phosphatidic acid is a simple and basic glycerophospholipid. It is an ester of glycerol with two long chain fatty acids at C1 and C2 position and phosphoric acid at C3 position. PA is synthesized by the hydrolytic action of phospholipase D on glycerophospholipids.


Egg PA is suitable for use:
  • in the preparation of reconstituted high density lipoprotein (rHDL) along with serum amyloid A (SAA)
  • as negatively charged lipid in the preparation of giant unilamellar vesicles
  • in the preparation of liposomes

Biochem/physiol Actions

Phosphatidic acid (PA) is involved in the synthesis of phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine and cardiolipin. PA functions as a signaling molecule.
