WebDiacylglycerol (DAG) is a glycerolipid with two fatty acyl chains attached to the central glycerol back bone [45]. It is also a potent second messenger signaling lipid often produced from the phospholipid phosphatidylinositol 4,5-bisphosphate by the enzyme phospholipase-C … 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 membrane curvature. • PA acts as a signaling lipid, recruiting cytosolic proteins to appropriate membranes (e.g., sphingosine kinase 1 ). WebDiacylglycerol kinases (DGKs) are a family of enzymes that catalyze the ATP-dependent phosphorylation of diacylglycerol (DAG) to phosphatidic acid (PtdOH). Despite the critical role in lipid biosynthesis, both DAG and PtdOH have been shown as bioactive lipids mediating a number of signaling pathways. trump\u0027s daughter with marla maples
