Electrophoretically distinct forms of galactose dehydrogenase were demonstrated in various tissues of the rat. Phylogenetic comparisons revealed considerable variation with species in mammalian liver zymograms; virtually no activity was demonstrable in fish, pigeon, and frog liver. Ontogenetic studies of the rat revealed sequential appearance of liver isoenzymes.
