In this pathway, the intermediate structures can be toxic, and health problems arise when those intermediates cannot be cleared. Pharmacokinetics, metabolism and pharmaceutics of drug of abuse.

Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator.
These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated aldehydes. Moser et al Progress in Chemical Toxicology.

The water is primed by a glutamate in the active site, and the water makes a nucleophilic attack on the carbonyl carbon, kicking off the sulfur as a leaving group. Cloning and characterisation of rabbit liver isoforms of the enzyme. ALDH2 plays a crucial role in maintaining low blood levels of acetaldehyde during alcohol oxidation.

Biology of Alcohol Problems. The enzyme’s active site then goes through an isomorphic change whereby the NAD P H is moved, creating room for a water molecule to access the substrate.

Aldehyde dehydrogenases EC 1. The metabolized acetaldehyde in the blood, which is six times higher than in individuals without the mutation, has shown to be a carcinogen in lab animals.
These enzymes are found in many tissues of the body but are at the highest concentration in the liver. These symptoms are the same as those observed in people who drink while adlehido treated by the drug disulfiramwhich is why it is used to treat alcoholism.
An important determinant of blood levels after alcohol consumption. A magnesium may be used to help the enzyme function, although the amount it helps the enzyme can vary between different classes of aldehydes.
