Early qualitative erythrocyte permeability studies (Gryns, 1896; Hedin, 1897) revealed the wide range of non-electrolyte permeability rates across a cell membrane composed of lipid molecules. Theoretically, water-soluble non-electrolytes such as glycerol, ethylene glycol and erythritol would penetrate less rapidly than lipid-soluble non-electrolytes. It was thought that the rate of penetration of water-soluble non-electrolytes was inversely proportional to their molecular size and the penetration of lipid-soluble non-electrolytes was directly proportional to their lipid-solubility.
