Finally, phospholipids serve as a reservoir for signalling molecules, such as arachidonic acid, phosphatidate, diacylglycerol and inositol trisphosphate. The scope of this review is the biological function and synthesis of the most abundant phospholipids in mammalian cells: phosphatidylcholine ... 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) to produce PA and choline. • By the phosphorylation of diacylglycerol (DAG) … See more • SK1 • PDE4A1 • Raf1 • mTOR • PP1 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. 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 the role of PA in the cell. However, PLD activity can be measured by the addition of primary alcohols to the cell. PLD then carries out … See more
