Potassium-adenosine triphosphate complex: formation constant measured with ion-selective electrodes

Potassium-adenosine triphosphate complex: formation constant measured with ion-selective electrodes

G A Rechnitz et al. Science. .

Abstract

Valinomycin and glass electrodes were used to measure activity of potassium ions in equilibrium with adenosine triphosphate. The thermodynamic formation constant of the complex is approximately 25 times greater than indirect measurements predict.
