[The role of boundary lipids in phase transitions of biological membranes].
In terms of the Landau thermodynamic expansion the model of lipid-protein interaction is considered for the case of relatively low protein concentrations. It is established that the proteins inserted into the lipid membrane can change its phase transition temperature. The expression determining the region size of the "boundary" lipids is obtained and the connection between the ordering extent of the "boundary" lipids and the sign and the value of the temperature shift of the phase transition is calculated.
