Role of Antioxidants and Natural Products in Inflammation

Table 1

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
