Part A. The Video Above Is An Introduction Of The Impact Of Radicals In  Health. 

Part A
The video above is an introduction of the impact of radicals in  health
  Use the internet to find images of at least 3 chemical  structures of antioxidants found in food and discuss how their  structural similarities explains their antioxidant activity
)Use  the  video as a reference for source of antioxidants
Part B
In our body, chemicals are transformed into more reactive molecules  that allows for a more efficient interaction with specific receptors or  enzymes
This increased reactivity may be due to conversion into highly  reactive intermediates such as: (1) electrophiles, (2) free radicals,  (3) nucleophiles, or (4) redox-active reactants
Use the internet or any other sources to find examples of the toxic  effect of these intermediates in our body and the biochemical reactions  they participate in our body
Which of the reactive intermediates mentioned here are responsible  for the depletion of the ozone layer? Give the name and the structures  of these compounds
