“Oxidoreductases”  [EC 1] 

Oxidoreductase Reactions

  In enzyme science, Oxidoreductase Reactions (Oxidoreductases), Dehydrogenases, are a group of broad Top-level Enzyme Reactions (Enzyme Catalysts) in the Top-level Enzyme Reaction Group EC 1, which catalyze oxidation/reduction reactions include the; transfer of H and O atoms or electrons from one substance to another substance.
  In biochemistry, an Oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule (the reductant, also called the hydrogen or electron donor) to another (the oxidant, also called the hydrogen or electron acceptor).

  The Oxidoreductases group of enzymes usually utilizes NADP or NAD as cofactors. *

“Superoxide Dismutase (SOD)”  

Superoxide Dismutases

  In our body, Superoxide Dismutase (SOD) is a class of metalloenzymes that catalyze the dismutation of superoxide into oxygen and hydrogen peroxide.

Three forms of Superoxide Dismutase (SOD)

  In our body, Superoxide Dismutase (SOD) is an oxidoreductase that catalyzes the reaction between superoxide anions and hydrogen to yield molecular oxygen and hydrogen peroxide. The Superoxide Dismutase, as an enzyme, protects the cell against dangerous levels of superoxide.

In our body there are three forms of superoxide dismutase (SOD).

• superoxide dismutase 1 (SOD 1), aka CuZn-SOD, is located in the cytoplasm
• superoxide dismutase 2 (SOD 2), aka Mn-SOD, in the mitochondria
• superoxide dismutase 3 (SOD 3), aka EC-SOD, is extracellular

  In our body, Superoxide Dismutase (SOD) catalyzes the removal of the O^2- free radical.

In our body, the enzyme Superoxide Dismutase (SOD) protects oxygen-metabolizing cells against harmful effects of superoxide free-radicals. Superoxide dismutase is inactivated by H₂O₂.

In our body, Superoxide Dismutase (SOD) consists of two subunits of identical molecular weight joined by a disulfide bond. The molecular weight is 32,500 daltons, and there are two Cu(II) and two Zn(II) atoms per molecule. **

“EC 1.3 Enzymes”  

Oxidoreductase Subclass Acting on the CH-CH Group of Donors

  In enzymology, Oxidoreductase Acting on CH-CH Donors (EC 1.3 Enzyme subclass) in the Oxidoreductase Class of enzymes are a subclass of oxidoreductase enzyme which includes all dehydrogenases acting on carbon-carbon bonds.

Oxidoreductases Acting on CH-CH Group Donors

  In biochemistry, the EC 1.3 Enzyme subclass ...
  The Oxidoreductases Acting on CH-CH Group Donors enzyme group includes all the enzymes that introduce double bonds into substrates by direct dehydrogenation of carbon-carbon single bonds. **
