Effect of Free Radical/Antioxidants in Human Body
Journal Title: International Journal of Medicine and Pharmaceutical Sciences (IJMPS) - Year 2018, Vol 8, Issue 2
Abstract
The presence of one unpaired electron in a molecule is called free radical. When oxygen interacts with certain molecules in chemical reaction it produces atoms or group of atoms with unpaired electrons called free radicals. These are highly reactive in nature, they start a chain reaction which adversely alters the lipids, proteins, and DNA structure of a cell which triggers a number of human diseases. Cells may function poorly or die if this occurs. The body has natural defense system of antioxidants which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged thereby preventing the effect of free radical. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient (vitamin) antioxidants are vitamin E, beta-carotene, and vitamin C. The body cannot produce these micronutrients on its own so they must be supplemented through diet. The present review provides an overview on of oxidative stress- mediated cellular damages and role of dietary antioxidants to counter its effect
