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 s ...

and phospholipid. The full name is 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine. It is an important phospholipid for biophysical experiments and has been used to study various subjects such as

lipid raft The plasma membranes of cells contain combinations of glycosphingolipids, cholesterol and protein receptors organised in glycolipoprotein lipid microdomains termed lipid rafts. Their existence in cellular membranes remains somewhat controversial ...
