1,2-Dipalmitoyl-sn-glycero-3-phosphorylglycerol (DPPG) is a phosphoglyceride acylated with palmitic acid and can be used to prepare liposomes with negatively charged hydrophilic head groups. Its phospho-polar head is linked to two non-polar lipids (palmitic acid/16:0) via a glycerol molecule. In water, the molecule can orient itself into a lipid bilayer and can be used for drug encapsulation, such as drug-loaded liposomes or nanoparticles.
