Haber–Weiss reaction
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:
The second step is the Fenton reaction:
Net reaction:
The reaction is named after Fritz Haber and his student Joseph Joshua Weiss.
