1,2-Dipalmitoyl-sn-glycero-O-ethyl-3-PC is a phospholipid containing the saturated long-chain (16:0) stearic acid inserted at the sn-1 and sn-2 positions and an alkyl group on the phosphate oxygen of the polar headgroup. Cationic phospholipids such as this have proved useful as DNA transfection agents and for studies of surface charge density within lipid bilayers.
