AI overview
I cannot write an accurate overview of antioxidants based solely on the provided context, as it contains only an image caption identifying glutathione as an antioxidant without explaining what antioxidants are, how they work, or why they matter. To provide an accurate and informative overview as requested, I would need additional factual information beyond what's available here.

Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals. Autoxidation leads to degradation of organic compounds, including living matter. Antioxidants are frequently added to industrial products, such as polymers, fuels, and lubricants, to extend their usable lifetimes. Foods are also treated with antioxidants to prevent spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol, or bacillithiol, and enzyme systems like superoxide dismutase, inhibit damage from oxidative stress.
