A proper description of the reactions of ferric cytochrome c with ionic reductants requires a study of the effects of ionic strength on these reactions. During the course of such experiments, it was found that in neutral solutions of very low ionic strength the reduction of ferric cytochrome c with ascorbate followed biphasic kinetics. These results are reported herein together with preliminary evidence for a possible conformation equilibrium of the protein in solutions of very low ionic strength.
