[Informative aspects of interaction between regulatory peptides and cellular membranes].

The mechanism of interaction between regulatory peptides (RP) and plasma membranes of target cells were discussed from the positions of the informative theory. Quantity of information in molecules of RP in the solution and the coefficient of excess in the binding of the RP with the cell plasma membrane were calculated. Participation of different membrane components in the informative signal transduction was characterized. Proceeding from the results of own experiments and data from literature the role of the membrane lipid matrix in interaction between RP and a cell was analyzed. A scheme of regulation of the RP information effect on the cell is suggested.
