The average adult human contains about 0.005% body weight of iron, or about four grams, of which three quarters is in hemoglobin – a level that remains constant despite only about one milligram of iron being absorbed each day,[142] because the human body recycles its hemoglobin for the iron...
(b) Molecular structure of the complex anion [FeIV(L-6H)]2 À in 3 showing the atomic numbering scheme (displacement ellipsoids are drawn at the 50% probability level). Carbon atoms are shown in dark grey, oxygen atoms in red, nitrogen in blue, iron in magenta and hydrogen in light ...
Thus, iron balance is mainly regulated at the level of absorption. In addition to total body iron, hypoxia and erythropoiesis also influence intestinal iron absorption by complementary mechanisms [2]. Much of the iron used for hemoglobin synthesis in erythropoiesis is recycled from erythrophagocytosis...
