Antioxidant
Also known as: antioxidants · redox defence
A molecule that neutralises reactive oxygen species, protecting cells from oxidative damage — e.g. glutathione.
An antioxidant is a molecule that safely absorbs or neutralises reactive oxygen species before they can damage cell components. The body runs a network of them, regenerating one with another.
Glutathione is the body’s master antioxidant, and antioxidant activity is a proposed mechanism for many research compounds, from GHK-Cu to methylene blue. It is the direct counter to oxidative stress.
