1,2-Dimyristoyl-sn-glycero-3-phosphatidyl-rac-glycerol, Na salt

1,2-Dipalmitoyl-sn-glycero-3-PG (1,2-DPPG) is a phospholipid containing the long-chain (16:0) palmitic acid inserted at the sn-1 and sn-2 positions. It can be used in the generation of micelles, liposomes, and other types of artificial membranes.

1,2-Dipalmitoyl-sn-glycero-3-phospho-rac-(1-glycerol) forms lipid bilayers. In the high temperature phase, the conformation of the chains is liquid-like. In the low temperature phases, the chains are stiff and parallel and they interdigitate.
