AGPAT, or acylglycerol-3-phosphate acyltransferase, is an enzyme that plays a crucial role in lipid metabolism. It catalyzes the conversion of glycerol-3-phosphate and fatty acyl-CoA into lysophosphatidic acid, which is an important precursor for the synthesis of various lipids, including triacylglycerols and phospholipids. This enzyme is found in various tissues, including the liver and adipose tissue, and is essential for maintaining energy balance and cellular function. Dysregulation of AGPAT activity can lead to metabolic disorders, highlighting its significance in fatty acid metabolism and overall health.
