DPPE-MPEG(2000) is a polyethylene glycol (PEG) derivative of 1,2-dipalmitoyl-rac-glycero-3-phosphoethanolamine (DPPE), characterized as a PEGylated phospholipid.
1,3-Dipalmitoyl glycero-2-phosphatidylethanolamine is a phospholipid incorporating saturated long-chain (16:0) stearic acid at the sn-1 and sn-3 positions, with phosphatidylethanolamine (PE) at the sn-2 position. Phosphatidylethanolamines, critical components of biological membranes, play essential structural and functional roles. Various PE types are instrumental in forming micelles, liposomes, and other synthetic membranes.
