Aldehyde dehydrogenases are a group of enzymes that catalyse the oxidation (dehydrogenation) of aldehydes. Multiple forms exist in mammals in the cytosol, mitochondria and endoplasmic reticulum. They have been classified as Class 1 (cytosolic), Class 2 (mitochondrial) and Class 3 (tumour and other isozymes). 3, record 1, English, - aldehyde%20dehydrogenase

Les aldéhydes déshydrogénases sont des flavoprotéines hépatiques qui captent les aldéhydes et les oxydent en acides. Il existe plusieurs isoenzymes catalysant ces réactions, dans le cytoplasme ou les mitochondries de nombreuses cellules : foie, rein, cerveau, globules rouges. Au cours de l'oxydation de l'acétaldéhyde, un coenzyme NAD+ est encore réduit, et l'acide acétique produit est lié au coenzyme A par une liaison riche en énergie. L'acétyl-CoA issu de ce métabolisme pénètre dans la mitochondrie devient un substrat du cycle de Krebs. 5, record 1, French, - ald%C3%A9hyde%20d%C3%A9shydrog%C3%A9nase

Acetaldehyde dehydrogenases ... are dehydrogenase enzymes which convert acetaldehyde into acetic acid. The oxidation of acetaldehyde to acetate can be summarized as follows: CH3CHO + NAD+ + CoA = acetyl-CoA + NADH + H+. 2, record 2, English, - acetaldehyde%20dehydrogenase

Aldehyde dehydrogenases have a broad substrate specificity. Oxidation of aldehydes is considered to be generally a detoxification reaction, removing the electrophilic products of alcohol oxidation. For example, alcohol dehydrogenase oxidizes ethanol to acetaldehyde, responsible for some "hangover" symptoms, and acetaldehyde dehydrogenase detoxifies this to acetic acid. 3, record 2, English, - acetaldehyde%20dehydrogenase
