[Structure formation in interphase adsorption layers of lysozyme at liquid boundaries]. / Strukturoobrazovanie v mezhfaznykh adsorbtsionnykh sloiakh lizotsima na zhidkikh granitsakh

In connection with the modelling of biomembranes regularities of the formation and development of interphase adsorption layers of lysozyme at liquid borders under different conditions and depending on the nature of carbohydrate phase were investigated by the determination of mechanical characteristics of such layers. The investigations carried out showed that the most solid layers appeared under the conditions which assured the formation of the maximum number of intermolecular bonds (which in a common case is performed with maximum disorderlinesss of the macromolecules which get at the interphase).

[Rheological studies of interphase adsorption layers of lysozyme at phase separation liquid boundaries]. / Reologicheskie issledovaniia mezhfaznykh adsorbtsionnykh sloev lizotsima na zhidkikh granitsakh razdela faz

Rheological studies of thin layers of biopolymers provide a principally new approach to the studies of the structure and functions of biomembranes. Rheological properties of interphase adsorption layers of lysozyme at different concentrations, temperatures and at the border with various carbohydrates. The values of moduli of fast elastic deformation E1s, slow elastic deformation E2s, equilibrium module of elasticity Es, viscosity of elastic aftereffect, plastic viscosity eta 0s and eta s for the interphase layers of lysozyme at liquid borders show that the interphase adsorption layers were solidlike, and the moduli of dimeric structure evaluated as volume ones correspond to the characteristics of normal elastomeres.
