A member asked:
Can you have a mature red blood cell that doesn't contain iron inside of it?
4 doctors weighed in across 4 answers
No: A mature red blood cell contains hemoglobin. And the hemoglobin molecule requires iron as a component. The iron is part of the "heme" subunit of the molecule, where it is bound within a structure called a "porphyrin ring". Hope that helps.

No: Mature red cells are full of hemoglobin, the oxygen carrying pigment. Iron is an important part of the hemoglobin.

Blood: Mature blood cells do not contain a nucleus. The heme part of the hemoglobin molecules have iron attached. This mechanism allows for oxygen to bind temporarily for transport throughout the body. If a person is very low in iron, this oxygen carrying capacity is also decreased.

No.: Red blood cells (RBC) contain the protein Hemoglobin (Hgb) which binds and carries oxygen to organs and tissues in your body. Each Hgb contains 4 iron molecules that help to temporarily binds and transport oxygen for release to the tissues.
