The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: alcohol dehydrogenase

Enzyme Commission Synonyms: aldehyde reductase, ADH, alcohol dehydrogenase (NAD), aliphatic alcohol dehydrogenase, ethanol dehydrogenase, NAD-dependent alcohol dehydrogenase, NAD-specific aromatic alcohol dehydrogenase, NADH-alcohol dehydrogenase, NADH-aldehyde dehydrogenase, primary alcohol dehydrogenase, yeast alcohol dehydrogenase

Standard Gibbs Free Energy (ΔrG in kcal/mol): 2.5417786Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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.
