How does the body excrete the extra electron in free radicals?

Question

Free radicals have unpaired valence shell electrons. Anti-oxidants can absorb the electron but how is it ultimately disposed of?

Answer 1

What you have to keep in mind is that the electric force is a billion billion billion billion billion times stronger than gravity (yes, that's a one followed by 36 zeroes). It takes a ludicrous amount of energy just to have a free electron wandering around.

And that probably tells you where they go - they STAY stuck to the antioxidants. Or more accurately, they cause a chemical reaction which turns the antioxidant into something else (which is why they're bad... they'll do that to anything). Then they leave the body when the antioxidants do.
