IRON METABOLISM Iron overload and chelation
Iron is one of the most common elements in nature. As a transition metal it is very efficient in electron transport and redox reactions. The proteins and enzymes in which iron is an essential component play a key role in respiration, energy production, detoxification of harmful oxygen species and cell replication. Despite the abundance of iron in nature, the solubility of its stable ferric form...
متن کاملBody iron metabolism and pathophysiology of iron overload
Iron is an essential metal for the body, while excess iron accumulation causes organ dysfunction through the production of reactive oxygen species. There is a sophisticated balance of body iron metabolism of storage and transport, which is regulated by several factors including the newly identified peptide hepcidin. As there is no passive excretory mechanism of iron, iron is easily accumulated ...
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...
متن کاملDisorders of iron metabolism. Part II: iron deficiency and iron overload.
MAIN DISORDERS OF IRON METABOLISM: Increased iron requirements, limited external supply, and increased blood loss may lead to iron deficiency (ID) and iron deficiency anaemia. In chronic inflammation, the excess of hepcidin decreases iron absorption and prevents iron recycling, resulting in hypoferraemia and iron restricted erythropoiesis, despite normal iron stores (functional iron deficiency)...
متن کاملIron overload.
Dietary copper in the U.S. often is lower than that proved insufficient for men and women under controlled conditions. Iron overload can have adverse effects on copper nutriture and can produce cardiac disease in people. The hypothesis that iron can interfere with copper utilization to produce adverse effects related to cardiovascular function was tested. Rats were fed a diet high in iron and m...
