WebApr 20, 2024 · One of the oldest redox system for the generation of free radicals is Fenton’s reagent, (Fe2+/ H2O2):3,4 Fe2++ HOOH →HO•+ HO-+ Fe3+ In this reaction, precisely one electron is transferred from the iron (II) ion to the peroxide, triggering its dissociation and the formation of an iron (III) ion. WebMost of the ·OH generated in vivo comes from iron‐dependent reduction of H2O2 [4, 5].
