Glutamate undergoes deamination, an oxidative reaction catalysed by glutamate dehydrogenase, as follows:

In the oxidative reaction, the positive holes react with the moisture present on the surface and produce a hydroxyl radical.

Furthermore, oxidative reaction of zirconium with water releases hydrogen gas, which partly diffuses into the alloy and forms zirconium hydrides.

Bilins are derived from the closed tetrapyrrole ring of haem by an oxidative reaction catalysed by haem oxygenase to yield their characteristic open chain.

The last step of the oxidative reactions in the pentose phosphate pathway is the production of ribulose 5-phosphate.

One such enzyme group, mixed function oxidases (MFOs), detoxify harmful plant compounds by catalyzing oxidative reactions.

Another oxidative reaction of PCC is its conversion of unsaturated alcohols or aldehydes to cyclohexenones.

For transition metals, oxidative reaction results in the decrease in the d to a configuration with fewer electrons, often 2e fewer.

It is often suggested that oxidative addition-like reactions are also involved in mechanisms of heterogeneous catalysis, e.g. hydrogenation catalyzed by platinum metal.

The photo-oxidation reactions include chain scission, cross linking and secondary oxidative reactions.
