1. Disaccharidase activities of the small and large intestines of the @entity1573 were studied. 2. Homogenates of the small intestine readily hydrolysed @entity7969 , @entity969 and @entity70475 ( @entity70475 ), hydrolysed @entity1132 slowly and did not hydrolyse @entity7970 and cellobiose. 3. Within the small intestine the disaccharidases were located mainly in the intestinal wall; the activity in the contents accounted for less than 5% of the total activity. 4. The disaccharidases were non-uniformly distributed along the small intestine, the activities being greatest in the middle section. 5. The disaccharidase activities increased with age between 1 and 43 days. 6. Homogenates of the large intestine and contents readily hydrolysed @entity7969 , @entity969 , @entity70475 and @entity1132 and hydrolysed @entity8692 and @entity7970 slowly. 7. The large-intestinal disaccharidases were located mainly in the contents. 8. Similar K(m) and pH optimum values were found for the maltase, sucrase and palatinase activities of the large and small intestines. 9. The lactase activity of the large intestine was markedly affected by diet and had different K(m) and pH values from the small intestinal lactase. 10. Low activities of intestinal disaccharidase were found in 12-day-old embryos and marked increases in the intestinal disaccharidases of the developing embryo occurred 2-3 days before hatching.
