It is water-soluble, so it mostly works in water-soluble environments like in the bloodstream. It donates its electrons to free radicals (atom, molecule, etc. ) Helps to protect dna, lipids, cells, and tissues from damage. Oxidation is when electrons are taken off of atoms. This can damage cells/tissues and their dna. This oxygen sometimes forms free radicals (or reactive oxygen species) during the process of energy metabolism.
