The name "dehydrogenase" is based on the idea that it facilitates the removal (de-) of hydrogen (-hydrogen-) and is an enzyme (-ase). Dehydrogenase reactions come most commonly in two forms: the transfer of a hydride and release of a proton (often with water as a second reactant), and the transfer of two hydrogens.
Alcohol dehydrogenase activity varies between men and women, between young and old, and among populations from different areas of the world. For example, young women are unable to process alcohol at the same rate as young men because they do not express the alcohol dehydrogenase as highly, although the inverse is true among the middle-aged.

Lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of pyruvate to lactate and back, ...
Glucose-6-phosphate dehydrogenase (G6PD or G6PDH) (EC 1.1.1.49) is a cytosolic enzyme that catalyzes the chemical reaction.
Aldehyde dehydrogenase is a polymorphic enzyme [3] responsible for the oxidation of aldehydes to carboxylic acids. [3] There are three different classes of these enzymes in mammals: class 1 (low K m, cytosolic), class 2 (low K m, mitochondrial), and class 3 (high K m, such as those expressed in tumors, stomach, and cornea). In all three classes ...
The oxoglutarate dehydrogenase complex has the same subunit structure and thus uses the same cofactors as the pyruvate dehydrogenase complex and the branched-chain alpha-keto acid dehydrogenase complex (TTP, CoA, lipoate, FAD and NAD). Only the E3 subunit is shared in common between the three enzymes. [1]
A man whose wife was on the American Airlines plane that collided with a U.S. Army Black Hawk helicopter in Washington, D.C. has revealed the final text he received from her before the crash. On ...
The malate dehydrogenase family contains L-lactate dehydrogenase and L-2-hydroxyisocaproate dehydrogenases. L-lactate dehydrogenases catalyzes the conversion of L-lactate to pyruvate, the last step in anaerobic glycolysis. The N-terminus is a Rossmann NAD-binding fold and the C-terminus is an unusual alpha+beta fold. [3] [4]
