Acyltransferases are a type of enzyme that facilitate the transfer of acyl groups from one molecule to another. These enzymes play a crucial role in various biochemical processes, including lipid metabolism and the synthesis of complex molecules. By transferring acyl groups, they help in the formation of important compounds like fatty acids and phospholipids. These enzymes are essential in both plants and animals, contributing to cellular functions and energy storage. Acyltransferases are involved in the biosynthesis of lipids, which are vital for cell membrane structure and function. Their activity is important for maintaining overall metabolic health and supporting various physiological processes.
