Diacylglycerol (DAG), also known as diglyceride, consists of two fatty acid chains and a glycerol molecule. It primarily exists in two forms: 1,2-diacylglycerol and 1,3-diacylglycerol. DAG can be synthesized via the phosphatidic acid pathway in the endoplasmic reticulum by the action of phosphatidic acid phosphatase or produced during the lipolysis of triglycerides (TAG) by TAG lipase. DAG is also a crucial substrate for the biosynthesis of triglycerides, which are essential for energy storage,
