Abstract

In this article are presented the results of thoretical and practical research of the cryogenic transformations in intermolecular protein interactions from biomembrane. It was relieved the performance of physicochemical processes in plama membrane of the cell, which depends on the level of protein matrix modifications and physicochemical changes of the proteins in membrane at the stages of prefreezing. Therefore, has been elucidated the mechanisms of cryodestruction which are specific reactions, conditioned by intermolecular interactions disorders of proteins. It was established that summary content of protein in rooster and ox sperm in cryoconservation does not support significant changes compared with individual spectrum of protein fractions. At cryoconservation, in seminal plasma, modification content of the α-, β- and γ-globulin is specific for rooster and bull, but in spermatozoa the dynamic value of α-, β- and γ-globulins exhibit stability with nonspecific character for the studied species.
