Abstract

Interactions between the ionophore nigericin AH and alkali metal cations M+ were studied using both potentiometry and calorimetry. Two types of complexes are formed: AHM+ and AM. Formation constants as well as ΔG, ΔH, and ΔS of formation are reported. These results are discussed in terms of the ‘open’ and ‘closed’ structure of various forms of nigericin (AH, A, AM, AHM+).
