Hydrogen peroxide

Description

Hydrogen peroxide, H₂O₂ or dihydrogen dioxide, is one of several reactive oxygen intermediates generally referred to as reactive oxygen species (ROS). It is formed in various enzyme-catalyzed reactions (e.g. superoxide dismutase) with the potential to damage cellular molecules and structures. H₂O₂ is dismutated by catalase to water and oxygen. H₂O₂ is produced as a signaling molecule in aerobic metabolism and passes membranes more easily compared to other ROS species.
