Role of Antioxidants on Cancer and Neurodegenerative Disorders

Prashanthi Gummadi

ABSTRACT Antioxidants are the substances which protects cells from damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer and many neurodegenerative disorders. Reactive oxygen species (ROS) over production will results in oxidative stress which can leads to neuronal damage and results in cancer and Neurodegenerative. An antioxidant defence mechanism involves removal of this reactive oxygen, nitrogen species and their precursors thereby inhibit formation of ROS. Scientific research confirms that free radicals have a major role in the development of cancer, heart disease, cataracts, aging and impairment of the immune system. Nutritional antioxidants might exert some protective activity on Alzimers Disease, Parkinson Disease. This review explains that how might antioxidants help in preventing cancer along with prospective study of antioxidants their mechanism and role in cancer therapy and the biochemical process by which antioxidants can prevent neuronal death occurring in neurodegenerative disorders.
