[Iron absorption].
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 ...
متن کاملMacromolecular Absorption
The immature small intestine of neonatal mammals is permeable to gamma globulins as a source of passive immunity. Allegedly, macromolecular absorption ceases when the epithelial cell membrane matures. However, some evidence exists that adult animals retain a limited capacity to transport antigenic and biologically active quantities of large molecules. In this study, the mechanism of absorption ...

Page 1 of 6 http://sickle.bwh.harvard.edu/iron_absorption.html Figure 1. Iron absorption. Iron enters the stomach from the esophagus. 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...
متن کاملPeritoneal Absorption
The absorption of red cells from the normal peritoneum of the dog can be demonstrated by means of red cells labeled with radio-iron incorporated in the hemoglobin of these red cells. Absorption in normal dogs runs from 20 to 100 per cent of the amount given within 24 hours. Dogs rendered anemic by bleeding absorb red cells a little less rapidly-ranging from 5 to 80 per cent of the injected red ...
متن کاملFolate absorption
Folic acid, or pteroylglutamic acid, is the parent substance of a large group of related compounds called 'folates'. All folate compounds have the same basic molecular structure consisting of three parts: pteridine, para-aminobenzoate (these two together forming a pteroyl group), and L-glutamic acid (Fig. 1). Pteroylglutamic acid itself is a stable, watersoluble compound with a molecular weight...
