1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine-N- (succinyl) sodium salt

1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine-N- (succinyl) (sodium salt) is a succinyl-modified phospholipid derivative (DPPE derivative) . The carboxyl group introduced into its polar headgroup provides additional negative charge and reactive sites, facilitating further conjugation with biomolecules or drugs. In liposomes and nanodelivery systems, such modified phospholipids are commonly used to regulate membrane surface charge and achieve functionalization, thereby improving the stability and targeting capabilities of the carriers.
