DPPE-PEG-Mal, MW 2K, derived from dipalmitoylphosphatidylethanolamine (DPPE), is significant in pharmaceutical R&D due to its drug delivery capabilities. A phospholipid, DPPE is key in cell membranes and is biocompatible. By adding a polyethylene glycol (PEG) chain for water solubility and a maleimide (Mal) group for bonding to cysteine residues, DPPE-PEG-Mal becomes essential for targeted drug delivery.
