| Pyruvate is first decarboxylated to produce acetaldehyde and carbon dioxide, catalyzed by pyruvate decarboxylase. |
| Another contributory factor is the conversion of alcohol to acetaldehyde by the liver. |
| Mix the diphenylamine reagent, as above, and split it into two aliquots before adding the acetaldehyde. |
| A second dehydrogenation turns acetaldehyde into acetic acid, aka vinegar, which gets digested as usual. |
| Ethanol is primarily metabolized to acetaldehyde by the action of alcohol dehydrogenase. |
| The enzyme aldehyde dehydrogenase is responsible for efficient metabolism of alcohol after it has been oxidised to acetaldehyde. |
