[The effect of the peptide constituents of casein hydrolysates on glucose and water absorption in the rat small intestine].

The effects of the peptide constituents of two casein hydrolysates applied to the serosal surface, involved the activation of the water absorption alone. Application of these peptides to the mucosal surface slightly inhibited both the glucose and water absorption. The data obtained suggests the mechanism of the peptides action on the glucose and water absorption in the small intestine.
