The metabolized acetaldehyde in alsehido blood, which is six times higher than in individuals without the mutation, has shown to be a carcinogen in lab animals.
Statements and hypotheses of present research. To date, nineteen ALDH genes have been identified within the human genome. Views Read Edit View history.
EC number Enzyme superfamily Enzyme family List of enzymes. Cloning and characterisation of rabbit liver isoforms of the enzyme. Effects on Biological Membranes.
These enzymes are found in many tissues of the body but are at the highest concentration in the liver. In this pathway, the intermediate structures can be toxic, and health problems arise when those intermediates cannot be cleared. The case againts first pass metabolism of the ethanol in the stomach.

The patients show higher blood levels of acetaldehyde, and become violently ill upon consumption of even small amounts of alcohol. Aldehyde dehydrogenases EC 1. These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated aldehydes.

ALDH2 (aldehído deshidrogenasa)
An important determinant of blood levels after alcohol consumption. Progress in Chemical Toxicology. Cys and Glu interact with the aldehyde substrate. The water is primed by a glutamate in the active site, ceshidrogenasa the water makes a nucleophilic attack on the carbonyl carbon, kicking off the sulfur as a leaving group.

Nippon Rinsho, 53, Kissin and Begleiter, Eds. The active site of the aldehyde dehydrogenase enzyme is largely conserved throughout the different classes of the enzyme and, although the number of amino acids present in a subunit can change, the overall function of the site changes little.
