Abstract:
With ageing the membrane/soluble form ratio of membrane-boundenzymes increases especially in the ileum and that of peptidases changes rather insignificantly in both portions of the rat small intestine. The soluble forms are supposed to take part in assimilation of food substrates penetrating enterocytes in an unsplit form due to an enhanced permeability of the membranes, particularly those of the ileum.
