Short Communication THE EFFECT OF THE PRESENCE OF CROWN ETHER ON ION TRANSPORT ACROSS THE LIPID BILAYER

By Monika Naumowicz, Aneta D. Petelska and Zbigniew A. Figaszewski

Abstract

Abstract: We studied the electric properties of phosphatidylcholine bilayers modified with crown ether (dibenzo[18] crown-6). The studies were carried out for various crown ether concentrations in forming solutions and various potassium ion concentrations in electrolyte solutions. The presence of crown ether in the membrane influences the membrane's impedance; there is a reduction in its resistivity, a decrease in its resistance of phase transfer and an increase in its capacity of phase transfer with an increase in crown ether concentration in the bilayer and in K + ion concentration in the electrolyte solution
