Ion transport across membranes mediated by carrier molecules may show rectification
phenomena either if the membrane is asymmetrical or if the aqueous solutions on both sides …

A theoretical treatment of the electrical conductance and tracer permeability of lipid bilayer
membranes in the presence of macrocyclic ion carriers is given. The analysis is based on …

Stationary conductance experiments on neutral and negatively charged bilayer membranes
in the presence of valinomycin or monactin agree with a recently proposed carrier transport …

Stationary electrical conductance experiments together with nonstationary relaxation
experiments allow a quantitative determination of rate constants describing carrier-mediated …

The molecular basis of ion transport across biological membranes is largely unknown at
present. Its study is complicated above all by the complex nature of living systems, which …

The mechanism of alkali-ion transport mediated by valinomycin (or similar macrocyclic
carriers) may be studied using artificial planar bilayer membranes. The rate constants of the …

The central purpose of this paper is to elucidate in a well defined system the meaning of
certain phenomena and concepts associated with the active transport of ions. To this end a …

Charge-pulse relaxation experiments of valinomycin-mediated Rb+ transport have been
carried out in order to study the influence of membrane structure on carrier kinetics. From the …

Lysine-valinomycin and two N∈-acyl derivatives are compared with respect to their potency
to transport Rb+ ions across thin lipid membranes. Lysine-valinomycin acts as a neutral ion …

The theory for the carrier transport of ions across lipid membranes is extended to consider
the potential dependence of the association-dissociation reactions between the carrier and …
