[Formation of quasilinear domain structures in lipid membranes].
The process of domain lipid structure formation in phoshatidylcholine layer is studied in the context of phase separation theory for two-component mixtures. Computer simulation has shown that as the result of distinctions of structure of hydrocarbon chain-in all-trans and gauche states phase separation of different lipid conformers occurs and quasilinear domain structure is formed in the region of pretransition. The repeat distance of obtained domain structure is reasonable agreement with the experimental data of the ripple mode in phase P beta, of phoshatidylcholine bilayer. Possible role of the In-plane quasilinear lipid structure in biomembranes is discussed.
