The ionization of human methaemoglobins A, S and C to their alkaline forms are measured at various ionic strengths and temperatures. An extrapolation function suggested by the theoretical work of Kirkwood, is used to calculate thermodynamic p K ’s, and hence standard free energies of ionization. Standard enthalpies and entropies of ionization are calculated from the temperature dependence of the ionization constants. Possible mechanisms by which the protein may affect the reactivity of the iron… CONTINUE READING
