| Description | Alcohol dehydrogenases (ADH) are a group of dehydrogenase enzymes that occur in many organisms and facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD+ to NADH). In Humans and many other animals, they serve to break down alcohols that otherwise are toxic, and they also participate in geneRation of useful aldehyde, ketone, or alcohol groups during biosynthesis of various metabolites. In yeast, plants, and many bacteria, some alcohol dehydrogenases catalyze the opposite reaction as part of fermentation to ensure a constant supply of NAD+. |
| Applications | Alcohol Dehydrogenase from Saccharomyces cerevisiae is used for gel filtration chromatography and as a gel filtration molecular weight marker. It has been used in bioelectrochemical research to investigate the use of diamond nanoparticles as a surface for protein loading. |
