The Haber–Weiss reaction generates •OH (hydroxyl radicals) from H2O2 (hydrogen peroxide) and superoxide (•O2−). This reaction can occur in cells and is therefore a possible source for oxidative stress. The reaction is very slow, but is catalyzed by iron. The first step of the catalytic cycle involves reduction of ferric ion to ferrous: :Fe3+ + •O2− → Fe2+ + O2 The second step is the Fenton reaction: :Fe2+ + H2O2 → Fe3+ + OH− + •OH Net reaction: :•O2− + H2O2 → •OH + OH− + O2 The reaction is named after Fritz Haber and his student Joseph Joshua Weiss. ==References== * * 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Haber–Weiss reaction」の詳細全文を読む スポンサード リンク
