Ethanol is first converted to a toxic intermediate, acetaldehyde, by ADH, then converted to acetate by wild type ALDH2*1. This can leave you abstaining from alcohol consumption altogether. 1, 2 Periodontitis, characterized by high prevalence, strong destructiveness, and complex pathogenesis, is very common worldwide. [Biological actions of acetaldehyde]. High acetaldehyde levels in saliva after ethanol consumption: methodological aspects and pathogenetic implications. Symptoms of an alcohol allergy include rashes, itchiness, swelling and severe stomach cramps. While the symptoms listed above are uncomfortable and at times dangerous, there are also more serious issues associated with alcohol consumption in ALDH2 deficient individuals.

Disruption of the Coenzyme Binding Site and Dimer Interface Revealed in the Crystal Structure of Mitochondrial Aldehyde Dehydrogenase Asian Variant. An enzyme's active site is like a keyhole: If a molecule fits into the active site, the enzyme changes shape in a way that makes a chemical reaction easier. Those who are ALDH2 deficient must be aware of this. ALDA-1 has been shown in studies to modulate the kinetic properties of the ALDH2 enzyme and increase its function dramatically. In general, fruits have more acetaldehyde than vegetables and other foods. Remember to avoid fermented foods, certain fruits, and drinks like coffee.
