General description

Ethanol-2-13C is an isotopic labeled precursor of ethanol.

Application

Ethanol-2-13C have been used as an internal standard to quantify the formed 2,4-dinitrophenylhydrazine using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). It can be used for enzymatic oxidation and metabolic flux analyses.

We describe a novel method for the determination of the concentration and labeling degree of ethanol originating from 1-13C-labeling experiments. This method is suitable for high-throughput metabolic flux analysis because of the possible parallel sample preparation and fast final analysis

Engineering microbes to utilize non-conventional substrates could create short and efficient pathways to convert substrate into product. In this study, we designed and constructed a two-step heterologous ethanol utilization pathway (EUP) in Escherichia coli by using acetaldehyde dehydrogenase (encoded by
