Abstract
A microscopic model of a lipid monolayer is proposed. It includes, within a single scheme, the following factors which are considered to be essential in phase transitions in lipid systems: formation of gauche rotamers, interactions between polar heads, interactions between hydrocarbon chains (depending on their conformation) and changes in the energy of the system due to a directional ordering of the chains. Phase diagrams are constructed and discussed and it is shown how the phase diagrams are modified by alterations of these parameters and the length of the hydrocarbon chains.
