    Iron in hemoglobin is the source of the red coloration of vertebrate blood. Hemoglobin diagram. Iron is an important biological element. [1] [2] [3] It is used in both the ubiquitous iron-sulfur proteins [1] and in vertebrates it is used in hemoglobin which is essential for blood and oxygen transport. [4]

  3. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and ...

    en.wikipedia.org/wiki/Human_iron_metabolism

    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 ...

    In addition, anemic patients may experience difficulties with memory and concentration, fatigue, lightheadedness, sensitivity to temperature, low energy levels, shortness of breath, and pale skin. Symptoms of severe or rapid-onset anemia are very dangerous as the body is unable to adjust to the lack of hemoglobin. This may result in shock and ...

  6. Anemia - Wikipedia

    en.wikipedia.org/wiki/Anemia

    Anemia or anaemia (British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.

  7. Carbaminohemoglobin - Wikipedia

    en.wikipedia.org/wiki/Carbaminohemoglobin

    When carbon dioxide binds to hemoglobin, carbaminohemoglobin is formed, lowering hemoglobin's affinity for oxygen via the Bohr effect. The reaction is formed between a carbon dioxide molecule and an amino residue. [12] In the absence of oxygen, unbound hemoglobin molecules have a greater chance of becoming carbaminohemoglobin.

  9. 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 ...
