Abstract
A number of fractions with differing intensity of the inhibitory action on the gastric secretion were obtained by gel filtration in a column with biogels P-30 and P-2 of cappa-casein glycomacropeptide. A low-molecular fraction displays the greatest capacity for inhibiting gastric secretion. Desialism, heating and partial hydrolysis of glycomacropeptide with pepsin, trypsin and chemotrypsin used separately have no effect on its inhibitory activity. The resulting data suggest that the inhibitory action of glycomacropeptide is caused by a certain part rather than by entire molecule.
