IntEnz Enzyme Nomenclature


Accepted name:
alcohol dehydrogenase
Other names:
NAD-dependent alcohol dehydrogenase
NAD-specific aromatic alcohol dehydrogenase
NADH-alcohol dehydrogenase
NADH-aldehyde dehydrogenase
alcohol dehydrogenase (NAD)
aldehyde reductase
aliphatic alcohol dehydrogenase
ethanol dehydrogenase
primary alcohol dehydrogenase
yeast alcohol dehydrogenase
Systematic name:
alcohol:NAD+ oxidoreductase




A zinc protein. Acts on primary or secondary alcohols or hemi-acetals with very broad specificity; however the enzyme oxidizes methanol much more poorly than ethanol. The animal, but not the yeast, enzyme acts also on cyclic secondary alcohols.
