Reaction catalyzed by lactate dehydrogenase. Lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD +.It converts pyruvate, the final product of glycolysis, to lactate when oxygen is absent or in short supply, and it performs the reverse reaction during the Cori cycle in the liver.
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.
Pyruvate dehydrogenase is an enzyme that catalyzes the reaction of pyruvate and a lipoamide to give the acetylated dihydrolipoamide and carbon dioxide. The conversion requires the coenzyme thiamine pyrophosphate. Pyruvate dehydrogenase is usually encountered as a component, referred to as E1, of the pyruvate dehydrogenase complex (PDC). PDC ...
The effects of the NAD + /NADH ratio are complex, controlling the activity of several key enzymes, including glyceraldehyde 3-phosphate dehydrogenase and pyruvate dehydrogenase. In healthy mammalian tissues, estimates of the ratio of free NAD + to NADH in the cytoplasm typically lie around 700:1; the ratio is thus favorable for oxidative reactions.

It is an X-linked recessive disorder that results in defective glucose-6-phosphate dehydrogenase enzyme. [1] Glucose-6-phosphate dehydrogenase is an enzyme that protects red blood cells, which carry oxygen from the lungs to tissues throughout the body. A defect of the enzyme results in the premature breakdown of red blood cells.
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 ...
