Diacylglycerol
Diacylglycerol is a
second messenger molecule made by
phospholipase C (a
membrane-bound
enzyme), together with
inositol triphosphate. Although inositol triphosphate diffuses into the
cytosol, diacylglycerol stays close to the
plasma membrane, due to its
hydrophobic properties.
Diacylglycerol has two major functions in the cell:
