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.
ethanol + NAD+ ↔ acetaldehyde + NADH + H+ (22.214.171.124)
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
Acts on primary or secondary alcohols or hemiacetals.
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 [a primary alcohol + NAD+ ↔ an aldehyde + NADH + H+] (126.96.36.199):
i1: ethanol + NAD+ ↔ acetaldehyde + NADH + H+ (188.8.131.52)
