Title: Free radicals Post by: shawn-dog on Oct 7, 2013 why are free radicals so dangerous to cells? How ae the dealt with by the body?
Title: Re: Free radicals Post by: blahtim on Oct 7, 2013 Free radicals are atoms/molecules with an unpaired number of electrons. This makes them highly reactive and they can start a chain reaction. The real danger for cells and the body comes in when these free radicals react with cellular components, for example with DNA. This can influence the working of the cell or even stop the cells activity completely. Because these free radicals form on natural basis (for example UV light enhances the formation of free radicals) the body has a defence meganism of antioxidants. These molecules bond with the free radicals and form, stop the chain reaction before any damage is done and form a unharmful molecule. Vitamine C for example is one of the most common antioxidants.
