| Clinical Use |
The enzymes collectively known as the mucosal disaccharidases (lactase, maltase, palatinase, and sucrase) are present in normal small intestine and fetal colon. Depending on the disease state, different enzymes are affected. A decrease in the enzyme activity of these disaccharidases has been noted in colonic adenomas, adenocarcinomas and malabsorption. Decreased disaccharidase activity is a good indicator of mucosal injury, with the exception of lactase. |
