General annotation (Comments)

Function	ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation By similarity.
Catalytic activity	An aldehyde + NAD(+) + H(2)O = an acid + NADH.
Pathway	Alcohol metabolism; ethanol degradation; acetate from ethanol: step 2/2.
Subunit structure	Homotetramer By similarity.
Subcellular location	Mitochondrion matrixBy similarity.
Sequence similarities	Belongs to the aldehyde dehydrogenase family.
