In 1956‚ Denham Harman articulated the free radical theory of aging which states that ‘oxygen free radicals that are formed endogenously in live cells result in a pattern of cumulative damage’(9). The theory is also implied that the target of those radicals in the cellular system is random. In live cells‚ DNA‚ protein and lipid are targets for the free radical’s invasion.
