ANTIOXIDANTS :SOURCES TYPES AND BENEFITS IN HUMAN BODY

 

"Antioxidants are those  substances which inhibits the process of oxidation".Normally our body posses lots of chemical reactions in the form of oxidation Which damages cell membranes and other structures, including cellular proteins, lipids and DNA. When oxygen is metabolized, it creates unstable molecules called ‘free radicals’, which steal electrons from other molecules, causing damage to DNA and other cells. .Which is harmful for the body.Antioxidants plays greater roles by inhibiting and by terminating the procedure of this oxidation.

It can be produced internally like glutathione and enzyme(catalyse,superoxide dismutase) or else you may also get it through dietary sources like vitamin A,vitamin C and vitamin E,lycopene,lutein.In certain types of industries it is used as presevatives to prevent oxidation and to give long lastic self life of specific products.
