| Common Name | 2,3-Butanediol |
|---|
| Description | 2,3-Butanediol is an isomer of butanediol. The 2R,3R stereoisomer of 2,3-butanediol is produced by a variety of microorganisms, in a process known as butanediol fermentation. 2,3-Butanediol fermentation is the anaerobic fermentation of glucose with 2,3-butanediol as one of the end products. The overall stoichiometry of the reaction is 2 pyruvate + NADH --> 2CO2 + 2,3-butanediol. Butanediol fermentation is typical for Enterobacter species or microbes found in the gut. 2,3-Butanediol has been identified in the sera of alcoholics and it may be a specific marker of alcohol abuse (PMID: 6139706 ). In humans, 2,3-butanediol is oxidized to acetyl-CoA via acetoin. 2,3-Butanediol is also found in cocoa butter. 2,3-Butanediol can also be found in Bacillus, Klebsiella and Serratia (PMID: 21272631 ). |
