[Effect of acetaldehyde upon the oxidative degradation of glucose by baker's yeast].
Acetaldehyde and glucose are simultaneously oxided by baker's yeast. By the use of 14C-U-glucose, as well as 14C-1 or 14C-6 glucose, it has been possible to demonstrate that glucose oxidation can partially be substituted by acetaldehyde oxidation. Acetaldehyde increases the 14C-1/14C-6 ratio of the evolved carbon-dioxide, thus stimulating the amount of glucose degraded by the phosphogluconate route and decreasing the amount metabolised by the glycolytic pathway.
