Concept #3: Digestion/Absorption of Proteins

Concept #4: Digestion/Absorption of Lipids

Practice: A 1-year-old boy presents to his pediatrician with severe, constant watery diarrhea. He is diagnosed with a genetic disease that is preventing him from absorbing glucose and galactose from his small intestine. His absorption of fructose is normal. Which of the following proteins is likely defective in this patient?

Practice: Which of the following enzymes is responsible for freeing single amino acids from the end of polypeptides?

Practice: A 45-year-old man has Whipple Disease, which causes obstruction of the lymph vessels (i.e. the lacteals) in the small intestine. The absorption of which of the following macronutrients is likely to be most affected by Whipple Disease?

Practice: A 45-year-old woman with an extensive history of Crohn Disease has a length of ileum resected (surgically removed). Because bile salts are reabsorbed in the ileum for recycling, she develops a bile salt deficiency. The absorption of which of the following macronutrients is likely to be most affected by a bile salt deficiency secondary to ileal resection?
