diacylglycerol A diglyceride, or diacylglycerol (DAG), is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Two possible forms exist, 1,2-diacylglycerols and 1,3-diacylglycerols. DAGs can act as sur ...

These lipases are widely distributed in animals, plants and prokaryotes. This family was also called class 3 lipases as they are only distantly related to other lipase families.
