The dismutation of formaldehyde by liver alcohol dehydrogenase.
The results obtained led the authors to the suggestion that Reactions 2 and 4 are catalyzed by liver alcohol dehydrogenase but that Reaction 1 is due to an aldehyde dehydrogenase present in their liver preparation. Because of the inhomogeneity of the enzyme preparation employed, a reinvestigation of this problem with more highly purified enzyme was suggested. With the use of crystalline horse l...
متن کاملDrosophila melanogaster alcohol dehydrogenase: mechanism of aldehyde oxidation and dismutation.
Drosophila alcohol dehydrogenase (Adh) catalyses the oxidation of both alcohols and aldehydes. In the latter case, the oxidation is followed by a reduction of the aldehyde, i.e. a dismutation reaction. At high pH, dismutation is accompanied by a small release of NADH, which is not observed at neutral pH. Previously it has been emphasized that kinetic coefficients obtained by measuring the incre...
متن کاملThe physiological role of liver alcohol dehydrogenase.
1. Yeast alcohol dehydrogenase was used to determine ethanol in the portal and hepatic veins and in the contents of the alimentary canal of rats given a diet free from ethanol. Measurable amounts of a substance behaving like ethanol were found. Its rate of interaction with yeast alcohol dehydrogenase and its volatility indicate that the substance measured was in fact ethanol. 2. The mean alcoho...
متن کاملReversible Oxidation of Cyclic Secondary Alcohols by Liver Alcohol Dehydrogenase
During a study of cyclic alcohol oxidation by a partially purified rat liver enzyme system (l), it was noted that ethanol was also oxidized by this preparation. Since the ratio of the rate of ethanol oxidation to the rate of cyclohexanol oxidation remained constant during purification, the possibility arose that the activity with cyclic substrates was due to the conventional alcohol dehydrogena...
متن کاملInhibition of Horse Liver Alcohol Dehydrogenase by Methyltin Compounds
The study of inorganic tin (SnCl(2), SnCl(4)) and methyltin compounds (MeSnCl(3), Me(2)SnCI(2), Me(3)SnCl) effects on the enzymatic activity of alcohol dehydrogenase (ADH) in the reaction of ethanol oxidation has been carried out. The experimental results of the study show that inorganic tin and methyltin substances induce slight inhibition of the catalytic activity of horse liver alcohol dehyd...
