The Specificity of Antioxidants: A Review
Abstract: Antioxidants are substances that provide protection to the body against reactive chemical species. When oxidative damage is not prevented or reversed, some pathology may occur. Naturally, there are enzymatic antioxidants (example: superoxide dismutase) and non-enzymatic (example: glutathione) in the cell, and some are incorporated through the diet (example: vitamins). These substances exhibit specificity when carrying out their activity, that is why it is necessary to experiment their effects on different …
