Diglyceride - Wikipedia
WEBA diglyceride, or diacylglycerol (DAG), is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. [1] Two possible forms exist, 1,2-diacylglycerols and 1,3-diacylglycerols.
Diacylglycerol - an overview | ScienceDirect Topics
WEBDiacylglycerol (DAG) A product of phosphatidylinositol 4,5-bisphosphate (PIP2) cleaved by phospholipase C (PLC). It serves as a second messenger activating some members of protein kinase C (PKC)s, and is readily converted to phosphatidic acid in the cell by the action of diacylglycerol kinases.

WEBThe formation of DAG can result in activation of protein kinase C (PKC), an enzyme that was first described in the late 1970s. At least ten isoforms of PKC, 70 to 80 kDa, may exist in mammalian tissues [25, 26]. Four conserved (C) and five variable (V) regions can be discerned (Fig. 21-5).
