Vitamin B12 Absorption Duodenum. They are responsible for hydrochloric acid secretion that helps break down food, activates enzymes, and maintains the stomach's low ph for antimicrobial protection. If the vitamin b12 is ingested in its protein bound form, it must first undergo a proteolytic cleavage in the stomach or duodenum where it will bind. The degradation of hc by pancreatic proteases and the ph change trigger the transfer of b12 to if in the duodenum. In the duodenum, digestive enzymes free the vitamin b12 from haptocorrin, and this freed vitamin b12 combines with intrinsic factor, a. A carrier glycoprotein (castle's gastric intrinsic factor) binds to vitamin b12 and delivers it to receptor sites on the brush border of the ileal. Normally, vitamin b12 is readily absorbed in the last part of the small intestine (ileum), which leads to the large intestine. A coherent vitamin b 12 (b 12) transport pathway from food to the body's cells has now been delineated;
