[Electron computer modeling of membrane structure and distribution of admixture particles in the lipid bilayer]

A simple molecular model of double lipid layer of the membrane is proposed. Equilibrium distribution of small hydrophilic particles between bilayer and contacting solution was studied by computer modeling. Connection between the concentration profile of the particles and its structural organization was considered. Special role of the bilayer central region was found. The results obtained qualitatively agree with the known experimental data.
