Effect of peroxodisulphate ions on functional behaviour of hemoglobin.
The influence of ammonium peroxodisulphate on the functional state of human hemoglobin was studied. The investigation techniques included: laser photolysis, spectrophotometry and pH measurements. Two different actions of the peroxodisulphate ions upon hemoglobin seem to occur; a) a proton consuming process and an increase of the 4th CO-binding rate constant, l'4, but not yet oxidation of the heme iron (when S2O8(2-) and heme concentrations were of the same order), and b) a marked oxidation effect (when S2O8(2-) was added in excess).
