Time dynamics of maltose, glycylglycine, glucose, and glycine hydrolysis and absorption in isolated loop of the small intestine was studied in chronic experiments on Wistar rats (group 1) after their transition from the standard diet to the protein-free one with enhanced content of carbohydrates. During protein starvation, there were different changes in the rates of glucose and glycine absorption, and glycylglycine hydrolysis and absorption in isolated intestinal loop, but to the end of the 2nd week they returned to the initial levels (for glucose and glycylglycine) or increased (for glycine). The rates of maltose hydrolysis and derived glucose absorption remained at the initial levels for the first days of protein starvation, decreased on the 5th day, and did not change afterwards. Maltase, alkaline phosphatase, and amino peptidase M activities, determined in homogenates of the small intestinal mucosa (per g of the tissue) after 2 weeks of protein starvation, were lower in the rats of group 1 in comparison with the rats of group 2, kept on the standard diet. Thus, under protein deficiency the hydrolytic and absorptive capacities of the small intestine correspond to both ingested food composition, and body requirements.
