Three main pathways for triacylglycerol biosynthesis include the sn-glycerol-3-phosphate and dihydroxyacetone phosphate pathways, which predominate in liver and adipose tissue, and a monoacylglycerol pathway in the intestines.In maturing plant seeds and some animal tissues, a fourth pathway has … WebThe final and the only committed step in the biosynthesis of TGs is catalyzed by acyl-CoA:diacylglycerol acyltransferase (DGAT) enzymes. The genes encoding two DGAT enzymes, DGAT1 and DGAT2, were identified in the past decade, and the use of molecular tools, including mice deficient in either enzyme, has shed light on their functions.
WebOct 27, 1998 · Acyl CoA:diacylglycerol acyltransferase (DGAT; EC 2.3.1.20) is a microsomal enzyme that plays a central role in the metabolism of cellular glycerolipids (for reviews, see refs. 1 and 2). DGAT catalyzes the only committed step in triacylglycerol synthesis by using diacylglycerol (DAG) and fatty acyl CoAs as its substrates.
