THE ROLE OF ANTIOXIDANTS IN HUMAN HEALTH MAINTENANCE: SMALL MOLECULES WITH INFINITE FUNCTIONSAbstract
Oxygen is a necessary element that controls many metabolic reactions in human body. Increased amount of oxygen in the body leads to continuous chain of events resulting in the formation of deleterious toxic free radicals which are capable of quenching the macromolecules including proteins and nucleic acids. To counteract the toxicity of the free radicals, human body synthesizes both enzymatic and non-enzymatic antioxidants. Non-enzymatic antioxidants are small molecules, capable of preventing the oxidative damage incurred by free radicals. Antioxidants also play crucial role in the controlling the health problems such as heart diseases, cancer, aging etc. which occur mostly due to accumulation of free radicals. The present review focuses on the various roles of antioxidants in maintaining the human health.
