WebFormation of Free Radicals: Free radicals are basically formed as accidental and deliberate by-products and phagocytosis from oxygen, H 2 O 2, etc. Some of them are superoxide (O 2− ), hydroxyl (OH. ), etc.Independent on the identity of the cellular O 2 -activator, the initial reduction product is always a super-oxide radical. Web2. Formation of OH: More than 97% of the O atoms which are formed by photolysis of ozone, react back again to ozone. Less than 3% start the formation of the most important radical in the atmosphere, OH. If two molecules or atoms collide to form a product, a third species M is needed to take away some excess energy.
