Abstract:
The stereochemical course of the reduction of acetaldehyde to ethanol was investigated by evaluating, with the enzymic system yeast alcohol dehydrogenase/diaphorase and g.c.-m.s., the configuration of [1-2H]ethanol obtained from [1-2H]acetaldehyde with different micro-organisms. Although only S-[1-2H]ethanol was formed, all the micro-organisms showed evidence of the existence of alcohol dehydrogenases with opposite stereospecificity.
