Iron's role

The iron intervenes in the constitution of the hemoglobin and the myoglobin.
These two compounds are involved in the cellular activity.

The hemoglobin, via blood vessels, shuttles oxygen from the lungs to every organs. There it exchanges the oxygen with carbon dioxide and then takes back this carbon dioxide to the lungs to eliminate it.

The myoglobin is in muscles. It grabs the oxygen brought by the hemoglobin and delivers it to the muscular cells.

Iron is also a part of numerous enzymes, is indispensable to our immun system and plays an important role in the learning process.
