The same hemoglobin molecule releases oxygen and takes on carbon dioxide.

The hemoglobin molecule fills up the red blood cells.

They usually affect the functionality and/or the stability of the hemoglobin molecule.

Oxygen is carried by the hemoglobin molecule in red blood cells.

But the rest of us have a hemoglobin molecule based on iron.

Iron is a component of the hemoglobin molecule in blood, used to transport oxygen to living cells.

The hemoglobin molecule is then pyridoxylated to raise its P50.

Once a hemoglobin molecule is glycated, it remains that way.

A hemoglobin molecule leaving the left side of the heart carries four oxygen molecules.

If one of her own hemoglobin molecules tried to get her attention, would she notice?
