| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | Alcohol dehydrogenase (ADH) is a zinc-containing enzyme, distribution in the body has a high organ specificity, the most abundant in the liver. In normal physiological metabolism, ADH can catalyze ethanol (alcohol) metabolism. |
| Use | Alcohol dehydrogenase can be used for the determination of alcohol content, blood alcohol concentration, clinical for the diagnosis of diabetes, liver necrosis and alcohol poisoning, assay of decarboxylase, qualitative determination of coenzyme I and reduced coenzyme I. The tetramer of alcohol dehydrogenase with a molecular weight of 141kDa contains four identical subunits. The active site of each subunit contains one zinc atom. Each active site also contains two reactive thiols and one histidine residue. Isoelectric point: 5.4-5.8 optimum pH:8.6-9.0 substrate: Yeast alcohol dehydrogenase reacts most easily with ethanol, and its reactivity decreases as the volume of alcohol increases or decreases. The reactivity with branched and secondary alcohols is also very low. KM (ethanol) = 2.1 × 10-3m (methanol) = 1.3 × 10-1m (isopropanol) = 1.4 × 10-1m inhibitor: compound capable of reacting with free thiol group, included are N-alkyl maleimides and iodoacetamide. Inhibitors of zinc chelators include 1, 10-phenanthroline, 8-hydroxyquinoline, 2,2 '-bipyridine, and thiourea. Inhibitors of substrate analogs, including β-nad analogs, purine and pyrimidine derivatives, chloroethanol, and fluoroethanol. Absorption coefficient: E1% = 14.6 (water, 280nm) |
| production method | with horse liver as raw material, it is extracted after grinding, and the supernatant is fractionated and precipitated with ammonium sulfate to obtain crude product, after dialysis and recrystallization, the pure product was obtained. |
