Glycerophospholipids are phospholipids built on a glycerol-phosphate scaffold. The illustrated two-acyl group form is common, but the subclass also includes other substitutions and one-chain derivatives. See IUPAC–IUB lipid nomenclature, Lip-2.2 and Lip-2.6.
phosphatidylserine is a glycerophospholipid with a serine-containing headgroup that is normally net negatively charged near physiological pH. Its leaflet distribution contributes to membrane surface properties and protein recruitment.
phosphatidylethanolamine is a glycerophospholipid with an ethanolamine headgroup. Its relatively small headgroup can favor negative monolayer spontaneous curvature, depending on chain composition and conditions.
Phosphatidylcholine, abbreviated PC, is a glycerophospholipid with a phosphate-choline head. Its zwitterionic head illustrates why a hydrophilic region need not have a nonzero net electric charge. See Lodish et al.: membrane lipids.
