The coordination number is six. Four of these sites are occupied by the nitrogens in the heme moiety, one is occupied by the nitrogen in the side chain of a histidine residue, and the remaining one is occupied by a loosely bound oxygen molecule.
The heme group within the hemoglobin molecule is what actually binds to the oxygen molecule. This process involves the iron atom within the heme group forming a reversible coordination bond with the oxygen molecule.
Iron is the element found at the centre of haemoglobin.
Iron. This element is found at the center of each hemoglobin molecule.
If a quarter of the mass of the molecule is iron and the mass of the molecule is 89600u, then the mass of iron is 22400u ... a quarter of the total mass.
One molecule of hemoglobin has 4 iron ions.
Hemoglobin contains a heme group with an Iron ion attached to it. The iron is what binds to O2.
The iron containing part of hemoglobin is the 'heme' molecule.
Iron is the nutrient at the center of the hemoglobin molecule, which is essential for carrying oxygen in red blood cells throughout the body.
i think that hemoglobin is combination of iron and other minerals in body(human)
