Impact of radicals in health

Part A.
The video above is an introduction of the impact of radicals in ÿhealth.ÿ Use the internet to find images of at least 3 chemical ÿstructures of antioxidants found in food and discuss how their ÿstructural similarities explains their antioxidant activity. )Useÿ the ÿvideo as a reference for source of antioxidants.
Part B.
In our body, chemicals are transformed into more reactive molecules ÿthat allows for a more efficient interaction with specific receptors or ÿenzymes. This increased reactivity may be due to conversion into highly ÿreactive intermediates such as: (1) electrophiles, (2) freeÿradicals, ÿ(3) nucleophiles, or (4) redox-active reactants.

Use the internet or any other sources to find examples of the toxic ÿeffect of these intermediates in our body and the biochemical reactions ÿthey participate in our body.
Which of the reactive intermediates mentioned here are responsible ÿfor the depletion of the ozone layer? Give the name and the structures ÿof these compounds.
