[Adaptation of rats to unusual protein products during transition to definitive nutrition].

The authors studied the adaptation of initial and final links of the proteolytic chain, and intermediate nitrogen metabolism, to unusual products--protein concentrate from yeast-saccharomyces and anchovy. A number of enzymes in the organs-producers were found to be activated due to intensification of a limited proteolytic reaction. It was established that the changes in the functioning of the proteolytic stage of the digestive-transport conveyor led to shifts in the amino-acid pool in the blood serum of experimental animals.

[Features of the digestive function of the intestines during intake of nontraditional protein].

Hydrolysis of modified walleye pollock protein under the action of pepsin pancreatic and intestinal enzymes was studied under conditions in vitro and in vivo. It was found that the degree of dissolution of bonds is decreased in the experiments in vitro by 18.05-24.
