isozyme phenotypes of alcohol dehydrogenase ( adh ) and aldehyde dehydrogenase ( aldh ) from human gastroendoscopic as well as surgical gastric biopsies were determined by starch gel electrophoresis and agarose isoelectric focusing . gamma gamma adh isozymes were expressed predominantly in the mucosal layer of the stomach , whereas beta beta isozymes were in the muscular layer .
