    Iron deficiency first affects the storage of iron in the body, and depletion of these stores is thought to be relatively asymptomatic, although some vague and non-specific symptoms have been associated with it. Since iron is primarily required for hemoglobin, iron deficiency anemia is the primary clinical manifestation of iron deficiency. Iron ...

    en.wikipedia.org/wiki/Hemosiderin

    Hemosiderin or haemosiderin is an iron-storage complex that is composed of partially digested ferritin and lysosomes. The breakdown of heme gives rise to biliverdin and iron. [1] [2] The body then traps the released iron and stores it as hemosiderin in tissues. [3] Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. [3]

    One major trigger for the production of many ferritins is the mere presence of iron; [9] an exception is the yolk ferritin of Lymnaea sp., which lacks an iron-responsive unit. [ 12 ] Free iron is toxic to cells as it acts as a catalyst in the formation of free radicals from reactive oxygen species via the Fenton reaction . [ 17 ]

  6. Iron deficiency - Wikipedia

    en.wikipedia.org/wiki/Iron_deficiency

    Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...

    *Iron = ~3 g in males, ~2.3 g in females Of the 94 naturally occurring chemical elements, 76 are listed in the table above. Of the remaining 18, it is not known how many occur in the human body. Most of the elements needed for life are relatively common in the Earth's crust.

  9. Iron-deficiency anemia - Wikipedia

    en.wikipedia.org/wiki/Iron-deficiency_anemia

    [21] [22] This is because iron deficiency impacts the development of the cells of the brain called neurons. When the body is low on iron, the red blood cells get priority on iron, and it is shifted away from the neurons of the brain. Exact causation has not been established, but there is a possible long-term impact from these neurological issues.
