Oestradiol changes the dielectric structure of bilayer membranes

European Biophysics Journal volume 16, pages 23–29 (1988)Cite this article

Abstract

The addition of the hormone Oestradiol to Phosphatidylcholine-Cholesterol membrane changes the frequency dependence of the membrane impedance. It increases severalfold the electrical admittance of the polar regions and consequently provides a conducting shunt from the hydrocarbon region to the aqueous phase.
