WebbThe digestion of protein starts in the stomach, where HCl and pepsin break proteins into smaller polypeptides, which then travel to the small intestine ( Figure 23.30 ). Chemical digestion in the small intestine is continued by pancreatic enzymes, including chymotrypsin and trypsin, each of which act on specific bonds in amino acid sequences. WebbThe intestinal absorption of vitamin D is similar to that of vitamin A and occurs by simple passive diffusion in the small intestine. Most of the absorbed vitamin D is taken up by the lymphatics in chylomicrons. The primary impact of a deficiency of vitamin D relates to its effect on Ca 2+ and Pi homeostasis.
