Although this is a powerful aldehyde detoxification mechanism, it is easily overwhelmed by the relatively large amounts of alcohol that are typically consumed with alcoholic beverages as compared to the amounts of alcohol and acetaldehyde that are produced through normal metabolism.

The accumulated acetaldehyde exerts its toxic effects by inhibiting the mitochondria reactions and functions. The alcoholic is a victim of a vicious circle;

Acetaldehyde produces unpleasant physiological reactions even at low concentration, so the presence or absence of the gene mutation affecting aldehyde dehydrogenase in turn affects drinking behaviors.

The team found that risk from ingesting acetaldehyde via alcoholic beverages alone may exceed usual safety limits for heavy drinkers. ... Their risk assessment study found that the average exposure to acetaldehyde from alcoholic beverages resulted in a life-time cancer risk of 7.6/10,000, with higher risk scenarios (e...

To explore the role of acetaldehyde in alcoholic cardiomyopathy, we generated transgenic mice with overexpression of the alcohol-metabolizing enzyme alcohol dehydrogenase (ADH) and the acetaldehyde-metabolizing enzyme mitochondrial aldehyde dehydrogenase (ALDH2), driven by myosin heavy chain and chicken beta-actin...

THE process for fixation of the intermediate products of alcoholic fermentation by living cells, discovered by Neuberg with the aid of bisulphite, has limitations on account of the toxicity and low power of the salt.
