Iron homeostasis and nutritional iron deficiency.
Nonheme food ferritin (FTN) iron minerals, nonheme iron complexes, and heme iron contribute to the balance between food iron absorption and body iron homeostasis. Iron absorption depends on membrane transporter proteins DMT1, PCP/HCP1, ferroportin (FPN), TRF2, and matriptase 2. Mutations in DMT1 and matriptase-2 cause iron deficiency; mutations in FPN, HFE, and TRF2 cause iron excess. Intracell...
متن کاملNutritional iron deficiency.
Iron deficiency is one of the leading risk factors for disability and death worldwide, affecting an estimated 2 billion people. Nutritional iron deficiency arises when physiological requirements cannot be met by iron absorption from diet. Dietary iron bioavailability is low in populations consuming monotonous plant-based diets. The high prevalence of iron deficiency in the developing world has ...

متن کاملAnemia, Iron Deficiency, and Iron Deficiency Anemia
Anemia is one of the most widespread public health problems, especially in developing countries, and has important health and welfare, social, and economic consequences. These include impaired cognitive development, reduced physical work capacity, and in severe cases increased risk of mortality, particularly during the perinatal period. There is also evidence that anemia may result in reduced g...
متن کاملIron Deficiency and Iron Overload.
Iron is essential to most, if not all, living organisms, and the higher animals and man have employed it for many purposes essential to life. The readiness with which iron undergoes oxidation and reduction is utilized in many of the enzymes of electron transport, and in a number of other enzymes whose function is not understood. Furthermore, the combination of iron with porphyrin and protein le...
