DSPG, also known as 1,2-Distearoyl-sn-glycero-3-phosphoglycerol, is a phospholipid molecule with phosphate polar head connected to two non-polar lipid (stearic acid) by a glycerol molecule. In water, the molecule can orient itself into lipid bilayer and can be used for drug encapsulation, such as drug loaded liposomes or nanoparticles.

1,2-Distearoyl-sn-glycero-3-phospho-rac-(1-glycerol) Sodium Salt is used to prepare polyethyleneglycol-modified liposomal doxorubicin for therapies against drug resistant tumors. It is also used in the PEGylated liposomal drug formulation of the anti-cancer agent oxaliplatin.
