dehydrogenase

(redirected from sorbitol dehydrogenase (SDH))
   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
dehydrogenase /de·hy·dro·gen·ase/ (de-hi´dro-jen-ās″) an enzyme that catalyzes the transfer of hydrogen or electrons from a donor, oxidizing it, to an acceptor, reducing it.
de·hy·dro·gen·ase (dh-drj-ns, -nz, d-hdr-j-)
n.
An enzyme that catalyzes the removal and transfer of hydrogen from a substrate in an oxidation-reduction reaction.

dehydrogenase [de-hi´dro-jen-ās″]
an enzyme that mobilizes the hydrogen of a substrate so that it can pass to a hydrogen acceptor.
glucose-6-phosphate dehydrogenase an enzyme necessary for the oxidation of glucose-6-phosphate, an intermediate in carbohydrate metabolism. Hereditary deficiency of this enzyme in the erythrocytes is associated with a tendency toward hemolysis upon ingestion of certain antimalarial agents and sulfonamide drugs and fava beans (see favism.
lactate dehydrogenase (LDH) an enzyme that catalyzes the interconversion of lactate and pyruvate. It is widespread in tissues and is particularly abundant in kidney, skeletal muscle, liver, and myocardium. It appears in elevated concentrations when these tissues are injured.

dehydrogenase
(dē´hīdroj´nās´),
n an oxidoreductase class (EC 1) enzyme that induces the transportation of electrons or hydrogen from a donor, which usually indicates the dehydrogenase, to an acceptor compound.

dehydrogenase
an enzyme that mobilizes the hydrogen of a substrate so that it can pass to a hydrogen acceptor, such as NAD+ or FAD+.

alcohol dehydrogenase
dimeric enzyme protein of the liver catalyzing the NAD+-linked dehydrogenation of ethanol to acetaldehyde.
glucose-6-phosphate dehydrogenase
see glucose-6-phosphate dehydrogenase.
glutamate dehydrogenase (GD), glutamic dehydrogenase
an enzyme that catalyzes the reversible reaction of glutamic acid into 2-oxoglutaric acid and ammonia. High concentrations occur in the liver of sheep, cattle, horses and dogs. Serum levels are useful in detecting hepatocellular damage in ruminants.
l-iditol dehydrogenase (ID)
a liver specific enzyme; serum determinations have been used in the horse to detect hepatocellular damage. Called also sorbitol dehydrogenase, SDH.
isocitrate dehydrogenase (ICD)
an enzyme found in high concentrations in many tissues. Two major forms of the enzyme, an NAD+-dependent ICD associated with the mitochondrial TCA cycle and a NADP+-dependent ICD associated with fat synthesis in adipose tissue and lactating mammary gland of ruminants or with steroidogenesis in endocrine tissues. Serum levels have been used to detect hepatocellular damage, but it is not highly specific.
lactate dehydrogenase (LDH), lactic acid dehydrogenase
an enzyme that catalyzes the interconversion of lactate and pyruvate. It is widespread in tissues and is particularly abundant in kidney, skeletal muscle, liver and myocardium. It appears in elevated concentrations when these tissues are injured. See also mouse lactic dehydrogenase elevating virus.
lactate dehydrogenase agent
polyol dehydrogenase
sorbitol dehydrogenase (SDH)

de·hy·dro·gen·ase (dē-hī'drō-jen-ās),
Class name for those enzymes that oxidize substrates by catalyzing removal of hydrogen from metabolites (hydrogen donors) and transferring it to other substances (hydrogen acceptors), which are thus reduced; most of the oxidative enzymes (oxidoreductases, EC class 1) perform their oxidations in this manner.

de·hy·dro·gen·ase (dēhī-drojĕ-nās)
Class name for those enzymes that oxidize substrates by catalyzing removal of hydrogen from metabolites (hydrogen donors) and transferring it to other substances (hydrogen acceptors).

de·hy·dro·gen·ase (dēhī-drojĕ-nās)
Class name for those enzymes that oxidize substrates by catalyzing removal of hydrogen from metabolites (hydrogen donors) and transferring it to other substances (hydrogen acceptors).
