Fig. 3

Percentage share of free Co(II) ion and complex forms at fixed equilibrium of O2 uptake reaction in the Co(II)–amac–Himid–O2 systems. l-α-amino acid (amac) = a alanine, b asparagine, c histidine. Internal diagrams show the equilibrium share of species other than the O2 adduct in an extended scale. Cadd O2 denotes the total concentration of the dioxygen adduct(with dioxygen bound both reversibly and irreversibly). L amac, L′ Himid. Molar ratio Co(II): amac: Himid = 0.3: 0.6:0.3 (mmol)
