  2. Human iron metabolism - Wikipedia

    The body regulates iron levels by regulating each of these steps. For instance, enterocytes synthesize more Dcytb, DMT1 and ferroportin in response to iron deficiency anemia. [13] Iron absorption from diet is enhanced in the presence of vitamin C and diminished by excess calcium, zinc, or manganese. [14]

    The body regulates iron levels by regulating each of these steps. For instance, enterocytes synthesize more Dcytb, DMT1 and ferroportin in response to iron deficiency anemia. [29] Iron absorption from diet is enhanced in the presence of vitamin C and diminished by excess calcium, zinc, or manganese. [30]

    Duodenal cytochrome B (Dcytb) also known as cytochrome b reductase 1 is an enzyme that in humans is encoded by the CYBRD1 gene.. Dcytb CYBRD1 was first identified as a ferric reductase enzyme which catalyzes the reduction of Fe 3+ to Fe 2+ required for dietary iron absorption in the duodenum of mammals. [5]

  5. Hepcidin - Wikipedia

    Hepcidin is a protein that in humans is encoded by the HAMP gene. Hepcidin is a key regulator of the entry of iron into the circulation in mammals. [6]During conditions in which the hepcidin level is abnormally high, such as inflammation, serum iron falls due to iron trapping within macrophages and liver cells and decreased gut iron absorption.

  6. Iron preparation - Wikipedia

    en.wikipedia.org/wiki/Iron_preparation

    The most significant factor regulating iron uptake is the amount of iron present in the body. Iron absorption increases with sufficient iron storage and vice versa. Increased erythrocyte synthesis also stimulates iron absorption in the gut. [15] Therefore, oral bioavailability of iron varies greatly, ranging from less than 1% to greater than 50 ...

  7. Human digestive system - Wikipedia

    The parietal cells in the fundus of the stomach, produce a glycoprotein called intrinsic factor which is essential for the absorption of vitamin B12. Vitamin B12 (cobalamin), is carried to, and through the stomach, bound to a glycoprotein secreted by the salivary glands – transcobalamin I also called haptocorrin, which protects the acid ...

    The stomach plays a major role in digestion, both in a mechanical sense by mixing and crushing the food, and also in an enzymatic sense, by digesting it. The following are enzymes produced by the stomach and their respective function: Pepsin is the main gastric enzyme.
