Phosphatidic acid precursor

WebMost phosphatidic acid is generated de novo via the Kennedy pathway with glycerol-3-phosphate as the precursor, but a second mechanism involves the action of a specific phospholipase D on phosphatidylcholine. The last can be a direct precursor for diacylglycerol production via the action of phospholipase C ... WebA. Phosphatidic acid PA is the precursor of many other phosphoglycerides. The steps in its synthesis from glycerol phosphate and two fatty acyl coenzyme A (CoA) molecules were illustrated in Figure 16.14, in which PA is shown as a precursor of triacylglycerol.

Phosphatidic acids are anionic phospholipids important to cell signaling and direct activation of lipid-gated ion channels. Hydrolysis of phosphatidic acid gives rise to one molecule each of glycerol and phosphoric acid and two molecules of fatty acids. They constitute about 0.25% of phospholipids in the bilayer. See more Phosphatidic acid consists of a glycerol backbone, with, in general, a saturated fatty acid bonded to carbon-1, an unsaturated fatty acid bonded to carbon-2, and a phosphate group bonded to carbon-3. See more Besides de novo synthesis, PA can be formed in three ways: • By phospholipase D (PLD), via the hydrolysis of the P-O bond of phosphatidylcholine (PC) … See more As PA is rapidly converted to DAG, it is very short-lived in the cell. This means that it is difficult to measure PA production and therefore to study … See more The role of PA in the cell can be divided into three categories: • PA is the precursor for the biosynthesis of many other lipids. • The physical properties of PA influence … See more • SK1 • PDE4A1 • Raf1 • mTOR • PP1 See more http://www.pharmacy180.com/article/phospholipid-synthesis-1921/
