The Role of Antioxidants on Cellular Aging
Keywords:Cellular aging, Free radical, Antioxidant
Aging is the multidimensional process of changes in physical, physiological and behavioral condition of a cell over time. It is characterized by decline of multiple physiological functions that increase the probability of homeostatic imbalance and cellular death. Various free radicals are produced due to endogenous oxidative reactions. These highly reactive atoms cause oxidative damage and shorten lifespan of a cell. The antioxidants are the molecules, which neutralize free radicals and delay the cellular aging.
