Acetoin is an important physiological metabolite excreted by many microorganisms. The excretion of acetoin, which can be diagnosed by the Voges Proskauer test and serves as a microbial classification marker, has its vital physiological meanings to these microbes mainly including avoiding acification …

Acetoin, a high-value-added bio-based platform chemical, is widely used in foods, cosmetics, agriculture, and the chemical industry. It is an important precursor for the synthesis of: 2,3-butanediol, liquid hydrocarbon fuels and heterocyclic compounds.

Acetoin; CAS Number: 513-86-0; EC Number: 208-174-1; Synonyms: 3-Hydroxy-2-butanone,Acetylmethylcarbinol; Linear Formula: CH3COCH(OH)CH3 at Sigma-Aldrich

Feb 21, 2022 · Acetoin (AC) is an important platform bulk chemical with versatile applications. It exists in two stereoisomeric forms: (3R)-AC and (3S)-AC. Both stereoisomers could be potentially applied in the pharmaceutical industry, agriculture, and in optically active α-hydroxyketone derivative synthesis.

(R)-acetoin is an acetoin. It has a role as a Saccharomyces cerevisiae metabolite. A product of fermentation. It is a component of the butanediol cycle in microorganisms. In mammals it is oxidized to carbon dioxide. (R)-acetoin has been reported in Streptomyces avermitilis and Corynebacterium glutamicum with data available. View More...
