摘要
Interaction between oxyhemoglobin and H2O2 was studied by the aid of stopped-flow time-resolved spectrophotometry. The consecutive reaction kinetics of oxyhemoglobin with H2O2 suggested the presence of an intermediate species. The influence of pH, concentration of H2O2, and temperature on the pseudo-first order rate constants was studied. The kinetic experiments performed at different temperatures allowed to calculate the activation energy. A reasonable mechanism was also proposed.
