Abstract
Revision of the own data of experimental studies of membrane hydrolysis and absorption of mono- and dimeric nutrients in the small intestine of rats for the last 30 years are presented. The results of investigations of digestion and absorption of carbohydrates (glucose and maltose) in vitro by the preparations of accumulating mucus and in vivo in the chronic experiments on isolated and
functioning portions of the small intestine of the rats are analyzed. In vitro test determined a concentration-dependent relationship between the protein and carbohydrate origin substrates with varying degrees of polymerization. The peculiarities of absorption of different concentrations of glucose and maltose in the presence of equimolar solutions of glycine and glycyl-glycine respectively were discussed. Analysis of the data of hydrolysis of different concentrations of maltose in vitro and in vivo was made, and the coefficients of conjugation of digestion of maltose and absorption of produced M-glucose were compared. The high stability of the free glucose transport system both in vitro and in vivo was found.
