Permeability studies on animal membrane/carbohydrate systems.
Hydrodynamic permeability measurements on water, and on aqueous solutions of D-glucose and sucrose of various concentrations, through frog-skin membrane were made. The conductance of the membrane equilibrated with the permeants was also measured. Some comments regarding the dependence of the permeability coefficient and the membrane conductance on the concentration were made. It was observed that the membrane behaves anisotropically in so far as the hydrodynamic permeability in concerned.
