Dgat enzymes and triacylglycerol biosynthesis
Webof TAG catalyzed by DGAT is the final and unique step in TAG formation. It is believed that DGAT diverts 1,2-DAG from membrane phos-pholipid synthesis into TAG synthesis. Two mam-malian DGATs have been identified, DGAT 1 and 2 [13]. Both enzymes are membrane-associ-ated and share similar biochemical functions and tissue expression … WebApr 6, 2024 · These enzymes also exhibit DGAT activity towards 1,2-DAG and 1,3-DAG, catalyzing two steps in the biosynthesis of TAG from monoacylglycerol . The highest activity of these enzymes is observed in the intestine, but lower activity is also present in the stomach, kidney, adipose tissue, and liver [ 195 ].
