Definition

Hydrogen peroxide (H2O2) is a reactive oxygen species (ROS) generated from molecular oxygen (O2). Although the controlled cellular production of H2O2 plays an important physiological role, high cellular levels of H2O2 can produce carcinogenic effects and induce cell death.

Characteristics

H 2O 2 is a pale blue liquid first isolated in 1818 by Louis Jacques Thénard. H 2O 2 has industrial and domestic uses (e.g., paper bleaching, chemical synthesis, laundry detergents, antiseptic for wound cleaning, etc.), and it is manufactured today through an autoxidation reaction using O 2 from the air. Cells of aerobic organisms also generate H 2O 2 from O 2. Most of the energy (ATP) that aerobic cells need to live is obtained through a process called oxidative phosphorylation (OXPHOS). In this process, ATP generation is coupled with a reaction in which O 2 is reduced [reduction/oxidation] to water (H 2O) by a mitochondrial protein complex called...
