Abstract
The hexokinase activity of different mucosae of the gastrointestinal tract of the male rats has been studied. The activity was definitely higher in the mucosa of the glandular part of the stomach than in the whole wall of the membranous part, but still somewhat lower than the activity in the upper part of the small intestine. The activity increased slightly along the first 3rd of the small intestine, but then decreased continuously toward the large intestine. The mucosal activity was about the same in the appendix as in the middle part of the small intestine, but lower in the large intestine than in the last 3rd of the small intestine. The activities of different parts of the mucosa of the gastrointestinal tract changed differently during storage at a low (4[degree]C) temperature. The activity was markedly lower in the liver than in the mucosa of the small intestine.
