1,2-distearoyl-sn-glycoro-3-phosphoethanolamine-polymethylene glycol-Cholesteriol is a phospholipid peg derivative used for lipid preparation.Phosphatized polyethylene glycol combines with hydrophilicity and hydrophobicity.Polyethylene glycol phospholipid liposomes form high-quality materials,which can be used for drug delivery,gene transfection and vaccine delivery.Cholesterol is not only the basic material of cell membrane and liposome,but also the indispensable and important material of animal tissue cells.It not only participates in the formation of cell membrane,but also is the raw material for the synthesis of bile acid,vitamin D and steroid hormones.
