Xenobiotics that target rapidly dividing cells result in epithelial villus atrophy. Specific biomarkers for small intestinal mucosal injury are limited. The enterocytes in the small intestinal mucosa contain digestive enzymes that digest specific foods while they are being absorbed through the epithelium. These enzymes include peptidase, sucrase, maltase, lactase and intestinal lipase. This is in contrast to the gastric glands of the stomach where chief cells secrete pepsinogen.
