List of free radicals and their reactivity.
| No. | Free radicals | Reactivity |
| 1 | Superoxide anion | Generated in mitochondria, cardiovascular system, and other cell types | 2 | Hydrogen peroxide | Formed in the human body by a large number of reactions and yields potent reactive species | 3 | Hydroxyl radical | Highly reactive and generated during iron overload and such conditions in the human body | 4 | Peroxyl radical | Reactive and formed from lipids, proteins, DNA, and sugar molecules during oxidative damage | 5 | Nitric oxide | Neurotransmitter and blood pressure regulation and can yield potent oxidants during pathological states | 6 | Peroxynitrite | Highly reactive and formed from NO and superoxide | 7 | Ozone | Present as an atmospheric pollutant and can react with various molecules |
