The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. 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): 2.541809 [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.
Instance reaction of [S-hydroxymethylglutathione + NAD(P)+ ↔ S-formylglutathione + NAD(P)H + H+] (184.108.40.2064):
i7: S-hydroxymethylglutathione + NAD+ = S-formylglutathione + NADH + H+ (1.-.-.-)
Instance reactions of [a primary alcohol + NAD+ ↔ an aldehyde + NADH + H+] (220.127.116.11):
i1: phytol + NAD+ → phytenal + NADH + H+ (18.104.22.168)
i2: 1-octanol + NAD+ = octanal + NADH + H+ (22.214.171.124)
i3: 1-hexanol + NAD+ ← hexanal + NADH + H+ (1.1.1.-)
i4: n-propanol + NAD+ ↔ propanal + NADH + H+ (126.96.36.199)
i5: ethanol + NAD+ ↔ acetaldehyde + NADH + H+ (188.8.131.52)
i6: butanal + NADH + H+ → n-butanol + NAD+ (1.1.1.-)
