a substance elaborated by the stomach and found in the gastric juices that binds to vitamin B12 and facilitates its absorption by the intestines.
A protein normally secreted by the epithelium (lining) of the stomach that binds vitamin B12, the intrinsic factor/B12 complex is selectively absorbed by the distal ileum (large intestine), though only the vitamin is taken into the cell.
glycoprotein secreted from the lining of the stomach involved in the absorption of vitamin B12.
Secreted by gastric mucosa; is essential for absorption of vitamin B12 - important for red blood cell production.
A glycoprotein, secreted by the parietal cells of the stomach, that facilitates the intestinal absorption of vitamin B12.
a substance produced by the mucosa of the stomach and intestines that is essential for the absorption of vitamin B12; "lack of intrinsic factor can result in pernicious anemia"
A mucoprotein found in the gastric juices which is necessary for the assimilation and absorption of cyano-cobalamin (extrinsic factor) contained in food, and essential for the absorption of vitamin B-12.
natural substance normally found present in the stomach essential to the metabolism of vitamin B12.
protein produced in the stomach required for absorption of vitamin B12 by the intestines
A special substance secreted by your stomach to allow you to absorb cobalamin from your food.
a substance secreted by the cells in the stomach necessary for the absorption of B12 (cobalamin)
Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of 12}} later on in the small intestine.
