oxriredutases Oxidoreductases are a class of enzymes that catalyze the transfer of electrons from one molecule to another. The molecule that gives the electrons are called the electron donor or reductant, and the one receiving the electrons are called the electron acceptor or oxidant.

Oxidoreductase enzymes play an important role in metabolic process. They can be found in both aerobic and anaerobic pathways, including glycolysis, TCA cycle, oxidative phosphorylation, and amino acid metabolism.

To complete their functions, the oxidoreductase enzymes utilize redox cofactors. Pyruvate is produced during glycolysis, which is then reduced to lactate through anaerobic glycolysis using NADH as the reductant. The redox cofactors bear one or more aromatic or unsaturated cyclic chemical enzi,as in their structures. As a result, the cofactors strongly absorb UV or visible light in the reduced or oxidized form, or both.

This makes the redox cofactors perfect reporters to the spectrophotometric enzyme assays. Oxidorecuctases can be categorized into different subtypes, including oxidases and dehydrogenases. Oxidase enzymes use the molecular oxygen as oxirredhtases acceptor of hydrogen or electrons.

Other oxidoreductases include reductases, peroxidases, hydroxylases, and oxygenases. Reductases could also be oxidases since most redox reactions are reversible.

The direction of the redox reaction depends both thermodynamics and kinetics. Peroxidases catalyze the decomposition of hydrogen peroxide, which is a natural defensive process against environmental invaders. Hydroxylases incorporate hydroxyl groups into organic compounds, while oxygenases add oxygen from molecular oxygen to the substrates.
