Electrokinetic Effects off Aqueous Acetone Transmitting Supported Lipid Membranes

Abstract

Electrokinetic phenomena like hydraulic permeability, electroosmosis, streaming potential and current of water -acetone mixtures of different compositions, through cephalin and phosphatidyl inositol membranes, supported by a pyrex sintered G 4 glass disc, have been studied. The results obtained have been analysed with the help of non-equilibrium thermodynamics. Onsager's reciprocal relation has found to be valid and the efficiency of the electrokinetic energy conversion for electroosmosis and the streaming potential has been calculated. The concentration dependence of the phenomenological coefficients L l± and L 12 has also been taken into account.

Studies on Electrokinetic Effects Across Supported Mixed Lipid Membranes

“…In previous studies, single lipid membranes, supported by pyrex sintered G 4 glass discs, have been considered and electrokinetic effects of water, acetone and their mixtures of various compositions have been measured [1][2][3], Water and acetone are present in most bookes of animals and the plasma membrane, surrounding a biological cell contains a mixture of lipids, proteins, enzymes etc. In order to have some basic information of the transfer of liquids across cellular membranes, artificial membranes, having two lipids together, were prepared.…”

Non-Equilibrium Thermodynamics of Electrokinetic Effects of Electrolytic Solutions Permeating Across a Lipid Membrane

“…In fact it is the solution which moves between the two cellular regions. The transport of liquid across artificial, supported lipid membranes has already been taken into account in our earlier studies [1][2][3]. Now the present work deals with the electrokinetic effects of dilute KC1 and NaCl solutions across the lecithin membrane.…”
