 Context examples 

This allele, which encodes aldehyde dehydrogenase X, mitochondrial protein, plays a role in the modulation of alcohol-derived acetaldehyde metabolism.

(ALDH1B1 wt Allele, NCI Thesaurus)

This protein is involved in the metabolism of alcohol-derived acetaldehyde.

(Aldehyde Dehydrogenase X, Mitochondrial, NCI Thesaurus)

Threonine is converted to glycine through the removal of an acetaldehyde group, and glycine is then converted to serine, then pyruvate.

Disulfiram irreversibly inhibits acetaldehyde dehydrogenase that oxidizes the ethanol metabolite acetaldehyde into acetic acid.

(Disulfiram, NCI Thesaurus)

Acetaldehyde is reasonably anticipated to be a human carcinogen.

(Acetaldehyde, NCI Thesaurus)

For most of us, an enzyme called aldehyde dehydrogenase 2 (ALDH2) breaks down acetaldehyde into acetate (a nontoxic metabolite) and removes other toxic aldehydes that can accumulate in the body.

(Alcohol Could be Toxic and Cause DNA Damage for Some People, NIH, US)

This leads to an accumulation of acetaldehyde that produces a variety of very unpleasant symptoms referred to as the disulfiram-alcohol reaction.

(Disulfiram, NCI Thesaurus)

(Alcohol Could be Toxic and Cause DNA Damage for Some People, NIH, US)

The normal, active form of ALDH2 creates a catalytic tunnel, a space within the enzyme in which acetaldehyde is metabolized.
