Definitions for "Diacylglycerol"
An intracellular second messenger, formed by the enzyme phospholipase C from membrane lipid.
Lipid produced by the cleavage of inositol phospholipids in response to extracellular signals. Composed of two fatty acid chains linked to glycerol, it serves as a signaling molecule to help activate protein kinase C.
DAG) Intracellular signaling molecule produced by cleavage of phosphoinositides in response to stimulation of certain cell-surface receptors; functions as a membrane-bound second messenger in inositol-lipid signaling pathways. ( Figures 20-4 and 20-37)
