Phosphatidic acids can be formed by the acylation of lysophosphatidic acids, the phosphorylation of diacylglycerols, or the removal of the choline group from phosphatidylcholine. They have important roles in intracellular and extracellular signaling. 1,2-Dipalmitoyl-sn-glycero-3-phosphate is a phospholipid containing the long-chain (16:0) palmitic acid inserted at the sn-1 and sn-2 positions. It is used in the generation of micelles, liposomes, and artificial membranes.
