Part 1: Oxidation and OH radicals - Harvard University

1. Hydroxyl radicals (OH) clean the air. Image: Elmar Uherek. Oxidation in a chemical sense does not necessarily mean a reaction with oxygen containing compounds, it is rather the loss of electrons. However, in the air, oxidation does generally involve the reaction of a chemical species with an oxygen containing compound.

• Free radicals generally migrate to the amorphous phase and the oxidation takes place in this phase. • The presence of metallic ions such as Cu, Mn, Fe, Co cause catalytic peroxide break down that accelerates the initiation of oxidation. • The permeability of oxygen into a polymer is a key factor that will affect the overall oxidation.

The foundational study (1st study in this eBook) showed hydrogen to be a selective antioxidant. Hydrogen is selective because it only reacts with cell damaging oxygen radicals like hydroxyl radicals. Hydroxyl radicals are the most cytotoxic (cell damaging). By reducing the occurrence of hydroxyl radicals, cells can function as they should.
