Small amounts are dissolved in the blood plasma and body fluids and is a constituent of a wide range of enzymes. Approximately 20% is deposited in the liver, bone marrow Alte, from where it can be mobilized when necessary.
Function: As a component of hemoglobin iron transporting oxygen from the lungs to all cells and carbon dioxide, the opposite path. It is part of enzymes in the mitochondria control cell respiration processes.
Consequences of deficiency: Iron deficiency occurs unable for reasons inadequate supply through diet, but perhaps the most common cause is problems with absorption in the intestine. Deficiency may also caused by deficit of stomach acid and lack of B6, B12, C, folic acid, zinc
. Iron Deficits can lead to anemia, cancer, liver disorders, chronic gout in the joints, and susceptibility to infection.
