[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.
