Electroneutral transport of monovalent ions by fatty acids
By means of ion-selective electrodes transport of H+ and K+ ions through model membranes was studied. The latter are fatty acid esters--impregnated nitroacetatecellulose ultrafilters. Fatty acids like nigericin were shown to be ion carriers and stimulate K+--H+-exchange. The velocity of H+ ions tran...

Summary: | By means of ion-selective electrodes transport of H+ and K+ ions through model membranes was studied. The latter are fatty acid esters--impregnated nitroacetatecellulose ultrafilters. Fatty acids like nigericin were shown to be ion carriers and stimulate K+--H+-exchange. The velocity of H+ ions transfer was proportional to the content of fatty acid in the membrane, it depended on the content of Mg+2 ions and decreased abruptly as a result of cooling-induced phase transition of the fatty acid. |
