Recent research suggests that the cell can produce antioxidants

Vitamin pills and other supplements do not stop cellular aging , scientists have discovered . But human cells are able to produce its own antioxidant that can fight harmful agents .

Oxidative stress occurs when reactive oxidants enter the cell . These molecules carry too much oxygen atoms and eager to get rid of them . When one of the oxygen atoms react with one atom of the protein in the cell , can alter and damage the protein .Pollutants such as cigarette smoke oxidants help build their ruin - but it was also made ​​in the human body through the respiratory network . There are about a dozen different oxidants , the most common are ozone ( O3 ) or free radicals ( unstable oxygen molecules ) . Even hydrogen peroxide ( H2O2 ), which - in liquid form - often part of the cosmetics , disinfecting or bleaching agent , is the oxidant .Until now , scientists thought that antioxidants can prevent oxidant damage in cells . Vitamin C , E , or beta - carotene ( provitamin A ) will basically help unload oxidants .Vitamin pills do not do the trickMost doctors would agree it's a good idea to include these vitamins as part of a healthy diet . But pills containing antioxidant rarely do the trick . They are not able to help in the fight against the aging process .

Tobias Dick , researchers at the German Cancer Research Center , found that the cells can produce its own anti - oxidant them - glutathione - which is against oxidants .cells againstGlutathione reacts with the oxidant - cells then isolated product . And from time to time , the cell is able to slowly dismantle it .Cells are much more resistant and stronger when it comes to oxidative stress than scientists previously assumed .

 
seen the carrier is responsible to dispose of oxidized glutathione . That's how to see that the previously isolated cells oxidized glutathione . Researchers hope to be able to manipulate the transport process to make the cells more resistant - or less resistant when it comes to cancer cells - against oxidative stress .Although cells can produce their own antioxidants , would still have to consume antioxidants through fruits and vegetables .
