WebPhosphatidic acid (PA) phosphatase,2 the enzyme that catalyzes the Mg2+-dependent dephosphorylation of PA to produce diacylglycerol (DAG) (Fig. 1), has emerged as a vital regulator of lipid homeostasis in eukaryotic organisms (1). The PA phosphatase reaction was first characterized in 1957 from chicken liver extracts by Smith et al. (2). Yet, the Synthesis of diacylglycerol begins with glycerol-3-phosphate, which is derived primarily from dihydroxyacetone phosphate, a product of glycolysis (usually in the cytoplasm of liver or adipose tissue cells). Glycerol-3-phosphate is first acylated with acyl-coenzyme A (acyl-CoA) to form lysophosphatidic acid, which is then acylated with another molecule of acyl-CoA to yield phosphatidic acid. …

WebFeb 6, 2024 · DAG can emanate from stored fat as triacylglycerol, as well as the glycerophospholipid phosphatidylinositol (PI). In order to produce DAG from triacylglycerol, one of the outer acyl-CoA groups is deacylated by a lipase. Conversely, DAG synthesis from PI requires removal of the inositol group. sign companies in new albany ms
