usual human livers contain two major aldehyde dehydrogenase [ ( aldh ) aldehyde : nad+ oxidoreductase ] isozymes -- i.e. , a cytosolic aldh1 component and a mitochondrial aldh2 component -- whereas approximately equal to 50 % of orientals are `` '' atypical '' '' and have only the aldh1 isozyme and are missing the aldh2 isozyme .
