Alkyl hydroperoxide reductase (ahp) function is to

• A. Degrade hydrogen peroxide
• B. Transport manganese
• C. Convert superoxide to hydrogen peroxide
• D. Reduce hydrogen peroxide

Answer: (D)

Alkyl hydroperoxide reductase is part of the cell’s peroxide detoxification system. Its job is to reduce hydroperoxides, including hydrogen peroxide, by using reducing power supplied through its partner proteins. In practice, it converts H2O2 to water (and organic hydroperoxides to their corresponding alcohols), neutralizing reactive oxygen species that would otherwise damage lipids, proteins, and DNA. This is why reducing hydrogen peroxide is the best way to describe its function. It doesn’t transport metals like manganese, and superoxide dismutase performs a different role by converting superoxide to hydrogen peroxide. While “degrade” hydrogen peroxide gets at the idea of removing it, the enzymatic action is specifically reduction, turning peroxides into less reactive molecules.
