Abstract

Membrane structure and crystal-liquid crystal phase transition behaviors were investigated for the water system of totally artificial lipids with cationic or anionic head group and two alkyl chains. These artifical lipids formed multilamellar liposomes composed of a bimolecular layer. The phase transition temperature from gel to liquid crystalline lamellae decreased steadily to a limiting temperature with an increase in water concentration up to the lipid fraction of 0. 80-0. 85. This kind of phase diagram means that the artifical lipids have characteristics of both thermotropic and lyotropic mesomorphisms. For the cationic artificial lipid, the thickness of the bimolecular lamella in a gel state was shorter than a bimolecular length calculated on the assumption of planar zigzag conformation of the alkyl chains.
