title: Hydride transfer stereospecificity of rat liver aldehyde dehydrogenases.
abstract: The stereospecificity of hydride transfer to NAD+ by several forms of rat liver aldehyde dehydrogenase was determined by a nuclear magnetic resonance method. The forms included several mitochondrial and microsomal isozymes from normal liver, as well as isozymes from xenobiotic-treated and tumor cells. The proton added to NAD+ comes exclusively from the aldehyde substrate and in all cases was A (pro-R)-stereospecific.
