Intrinsic factor. Intrinsic factor. a mucoprotein normally secreted by the epithelium of the stomach and that binds vitamin b12, the intrinsic factor/B12 complex is selectively absorbed by the distal ileum, though only the vitamin is taken into the cell.ntrinsic factor.

intrinsic factor a glycoprotein secreted by the parietal cells of the gastric glands, necessary for the absorption of cyanocobalamin (vitamin B 12).Its absence results in pernicious anemia.ntrinsic factor forms a bond with molecules of cyanocobalamin, and this complex is transported across the ileal membrane. A deficiency of intrinsic factor, caused by gastrectomy, myxedema, or atrophy of the gastric mucosa, causes pernicious anemia.
