Abstract
The shape of the energy barrier inside thin, insulating membranes can be an important factor in determining the detailed behavior of transmembrane ionic flows. In particular, a model is developed in which the shape of the barrier is expected to have direct influence on such experimentally important membrane properties as: (a) the shape of the current-voltage relation; (b) the dependence of zero current conductivity on asymmetric concentrations; (c) the dependence of the rectification ratio on the concentration ratio. Current-voltage curves were measured for a wide range of symmetrical and asymmetrical concentrations in black lipid (phosphatidyl ethanolamine) films in the presence of nonactin and potassium. A single barrier shape was found to describe accurately the experimental results in terms of the model.
