Saliva also contains a glycoprotein called haptocorrin which is a binding protein to vitamin B 12. [17] It binds with the vitamin in order to carry it safely through the acidic content of the stomach. When it reaches the duodenum, pancreatic enzymes break down the glycoprotein and free the vitamin which then binds with intrinsic factor.
