Note that this reaction equation differs from the official Enzyme Commission reaction equations for this EC number, which can be found here and here .

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): 2.541809Inferred 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.

i1: butanal + NADH + H+ → n-butanol + NAD+ (1.1.1.-)

i2: n-propanol + NAD+ ↔ propanal + NADH + H+ (1.1.1.1)

i3: ethanol + NAD+ ↔ acetaldehyde + NADH + H+ (1.1.1.1)

i4: phytol + NAD+ → phytenal + NADH + H+ (1.1.1.1)

i5: 1-octanol + NAD+ = octanal + NADH + H+ (1.1.1.73)

i6: 1-hexanol + NAD+ ← hexanal + NADH + H+ (1.1.1.-)
