Hemoglobin's ironRed blood cells contain hemoglobin, a substance which is rich in iron. The iron is bound to the hemoglobin molecules (the protein). The iron atom that is complexed by "haem" units is what gives the color. Iron is a transition element.
it is needed to form reb blood cells... esential component of haem molecule
Engine exhaust, grills, and cigarettes. Carbon monoxide is a gas that is produced from these subjects.
Gases are carried in different ways in human blood. Some gases are bound to haem moieties and some gases are merely dissolved in the plasma. Without knowing to which gases you are referring, one would not be able to provide a definitive answer.
Haemoglobin (HB) is synthesised by the erythroid cells of the red bone marrow. HB is first seen at the state of internediate normoblast. Four molecules of prophobinlinogen combine and after some further changes protoprophynin is formed. Protoprophynin now incorporates with iron atoms to become haem. 4 heam molecules combine with one globin molecule to form one molecule of haemoglobin.
There are four atoms of iron in a molecule of hemoglobin. Each iron atom is attached to a porphyrin, forming a heme group. Each heme group is attached to a polypeptide chain. There are two alpha and two beta polypeptides. So a hemoglobin molecule has four heme groups, and four polypeptides.
haem part of haemohlobin is a metaloporphyrin, a tetrapyrrole ring with one fe2+ attached to the four nitrogen atoms from four pyrrole rings.

The red blood cells contain a globular protein called Haemoglobin, which carries oxygen by combining the oxygen molecules to its haem groups.
Liver, Red meat ....
Red meats are the best sources of ferrous sulfate (iron). Green veg are a good sources, but the iron is "non-haem" iron, which is less easily absorbed by the body. Only meat contains haem iron. Dried fruit also contains some (non-haem) iron. Also, shellfish is a fairly good source of (haem) iron, as is kidney and liver (from any animal).

Iron (Fe). It is the central ion of the Haem subunit.
Protein to create globin. Iron to create haem.
