Physiol. 2 I I (5) : I I 23-1 I 30. rg66.-Hemoglobin-iron was absorbed by the guinea pig as an iron-containing porphyrin compound. Absorption of both inorganic and hemoglobin-iron occurred primarily in the duodenum but about onethird of the quantity absorbed from the gut can be ab...
متن کاملThe Absorption of Hemoglobin Iron
The accepted mechanism of absorption of iron by the gastrointestinal tract involves solution and reduction to the ferrous form before its uptake by the mucosal cell (1). Food iron, much of which is bound in organic complex, has been assumed to follow the same pathway with the assistance of the digestive enzymes. Studies supporting this hypothesis have been conducted mainly with iron salts, and ...

Physiological control over iron balance is normally exercised through the regulation of iron absorption. Although it is known that the intestinal epithelium can reject unwanted dietary iron or absorb increased amounts when stores are low it is not known how iron crosses the epithelial cell or how this regulation is mediated. The principal factors which affect absorption are those acting in the ...

Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+ . Intestinal mucosal cells in the duodenum and upper jejunum...
