Guest guest Posted April 15, 2011 Report Share Posted April 15, 2011 << b12 must be protected from stomach acid and it has bigmolecules anyway his disolves in the intestines. >>This may be so, but bod protects it."Upon entry into the stomach, vitamin B12 becomes bound to haptocorrin (R factor), a glycoprotein. The resulting complex enters the duodenum, where pancreatic enzymes digest haptocorrin. In the less acidic environment of the small intestine, B12 can then bind to intrinsic factor. This new complex travels to the ileum, where special epithelial cells endocytose them. Inside the cell, B12 dissociates once again and binds to another protein, transcobalamin II. The new complex can exit the epithelial cells to enter the liver." Wikipedia on B12. H in Washington State Any sufficiently advanced technology is indistinguishable from magic.
