Question

where does all the hydrogen peroxide in our body comes from

Answer 1

Hydrogen peroxide (H2O2) is produced in the body as a byproduct of several metabolic processes. The primary source of hydrogen peroxide in our body is the enzyme called superoxide dismutase, which converts the superoxide anion (O2-) into hydrogen peroxide. It is also produced as a result of various cellular reactions involving oxygen metabolism. Additionally, our cells maintain a delicate balance of hydrogen peroxide through the action of various enzymes that break it down, such as catalase and glutathione peroxidase.
