smoke and sun exposure, can produce them,

too. The oxygen free radicals react with and

create instability in surrounding molecules.

This process, called oxidation, occurs as a chain

unstable; molecule “A” attempts to stabilize

itself by reacting with neighboring molecule “B”;

then molecule “B” is unstable and attempts to
