Characteristics of the chemiluminescence of the system containing H202 in the presence of iron compounds

: The relative effectiveness of radical formation by different concentrations of hemoglobin, hemin and Fe2+ in the reaction with H2O2 evaluated by the intensity of chemiluminescence was studied. Hemoglobin was shown to be remarkably effective at the concentrations close to those in blood plasma. It is suggested that exoerythrocyte hemoglobin and the products of its destruction up to hemin are the most effective prooxidants and potential centers of radical formation in the blood.
