| Abstract: | An important biochemical reaction of GSH with sodium selenite in the-presence of H_2O_2 is studied. It is shown by ESR and autooxidation of Pyrogallol that the superoxide radicals O2 are generated during the reaction in which sodium selenite acts as a catalyst. More O_2 has been found to be-generated to H_2O_2 than to O_2. |
