Product Name: Dehydrogenase
Synonyms of Dehydrogenase (CAS NO.9035-82-9): Oxidoreductases ; EINECS 232-907-4
CAS NO: 9035-82-9

A Dehydrogenase (CAS NO.9035-82-9) is an enzyme that oxidizes a substrate by transferring one or more hydrides (H⁻) to an acceptor, usually NAD⁺/NADP⁺ or a flavin coenzyme such as FAD or FMN. And dehydrogenases are belongs to the EC 1 Oxidoreductases group.
Aldehyde dehydrogenases is one kind of  dehydrogenases. Aldehyde dehydrogenases are a group of enzymes that catalyse the oxidation (dehydrogenation) of aldehydes.The active site of the aldehyde dehydrogenase enzyme is largely conserved throughout the different classes of the enzyme and, although the number of amino acids present in a subunit can change, the overall function of the site changes little.
The overall reaction catalysed by the aldehyde dehydrogenases is:
    RCHO + NAD+ + H₂O → RCOOH + NADH + H+

The nomenclature of Dehydrogenase (CAS NO.9035-82-9) is as following:
The common scheme for making names for oxidoreductases is adding donor name to the it, i.e. donor dehydrogenase. For example: alcohol it, leucine it etc. The proper name consists from the donor name, acceptor name together with oxidoreductase, i.e. donor:acceptor oxidoreductase. Sometimes the construction acceptor reductase is used. Here take Enzyme EC 1.1.1.1 for example, its systematic name is alcohol:NAD⁺ oxidoreductase, and its accepted name is alcohol it.
The catalytic mechanism of it is as following:
They transfer protons to an acceptor or coenzymes, i.e. small organic molecules, involved into enzymatic catalysis, such as Nicotinamide adenine dinucleotide (NAD⁺ or NADH), Nicotinamide adenine dinucleotide phosphate (NADP⁺ or NADPH), Flavin adenine dinucleotide (FAD) or Flavin mononucleotide (FMN).
