[Effect of the dielectric permeability of the non-aqueous phase on enzymatic charge transfer through an oil-water inferface].

Charge transfer across the interface between two immiscible liquids in functioning enzyme membrane systems and chlorophyll is studied. Phenomenological theory is developed describing the influence of the dielectric permeability of oil phase on the change of the potential difference at the interface during the charge transfer across oil/water. It is shown that change of the potential difference when varying dielectric permeability can be explained as a change of the activation energy of charge transfer and as change of the capacity of double electric layer. The theory is compared with experimental data based on the vibrating capacitance method in charge transfer during the action of soluble mitochondrial or bacterial ATPases and chlorophyll.
