Defence against free radicals
Most free radical reactions in the body involve initial attack
by oxygen free radicals. Compounds that provide a defence
against free radical oxidation are antioxidants and act in one
of two ways:
- Preventative antioxidants inactivate free radicals before
they have chance to initiate an oxidation chain reaction.
- Chain-breaking antioxidants interfere with an oxidation
chain once it has started by trapping free radicals and
terminating the reaction.
and natural free radical scavengers like vitamin C and E
(contained in partypacks). These cannot completely control the
free radicals, some of them do escape and cause damage, which
can accumulate over the years if preventative action is not taken.
