The conformational behaviour and the charge distribution of methylphosphorylcholine has been analyzed within the framework of the PCILO method including phosphorus-oxygen o-and 7r-bonds. In the global minimum of energy the -O-P-O-C-C chain has a (-synclinal, -synclinal, -syn/anticlinal, +anticlinal)

A modified CNDO-APSG procedure to obtain the charge distributions of the headgroups of phosphatidylserine, -ethanolamine and -choline as monomers and as constituents of hexagonal lattice is presented. The calculated charge distributions are typically zwitter-ionic. There is only a small difference b
