1,2-Dipalmitoyl-sn-glycero-3-N-methyl-PE is a form of 1,2-dipalmitoyl-sn-glycero-3-PE (1,2-DPPE; ) that contains a methyl group on the sn-3 moiety. The methylated headgroup of 1,2-dipalmitoyl-sn-glycero-3-N-methyl-PE does not extend as far into the aqueous subphase as the amine headgroup of 1,2-DPPE when incorporated into a water surface monolayer. It also lowers the phase transition temperature compared with 1,2-DPPE.
1,2-Dipalmitoyl-sn-glycero-3-phospho-(N-methyl)-ethanolamine is a phospholipid derivative that is a component of the lipid bilayer of the cell membrane. It is used to study monoclonal antibodies that specifically bind to phosphatidylcholine as well as in membrane permeability studies.
