Intrinsic component attaches B12 to unique ileal mucosa receptors allowing the complicated to become internalized by endocytosis to the enterocyte and produced into the bloodstream where by it can be certain to transcobalamin I, II, or III. fifty% of transcobalamin II sure B12 is taken up with the liver, in which it's stored though the rest is transported to other tissues. B12 is excreted in bile, but nearly all of it ends up reabsorbed.[nine]

Copper absorption largely happens during the modest intestine. Copper is taken up by enterocytes with copper transporter 1 (CTR1), that is a copper importer Found in the apical membrane of intestinal cells and many tissues. Copper is exported from the enterocytes to the blood by the exporter ATP7A. In portal circulation, almost all of the copper is bound to the transporter protein ceruloplasmin.
