What is the molecular weight (mw) of alcohol dehydrogenase (ADH)?

Posted June 1, 2018


82 kDa


Alcohol dehydrogenases (ADH) oxidises alcohol into aldehydes orketones. The enzyme occurs in various mammalian tissues but is found in relatively high concentrations in liver and kidney. Alcohol dehydrogenase from equine liver is a homodimer with a molecular weight of 82,000 daltons, which is equivalent of 82,000 g/mol. Each monomer contains 374 amino acids and has a mass of 41 kDa.
