How many molecules of Haemoglobin is there in ONE healthy normal red blood cell (RBC)?

Question

You may be able to use the molecular weight of hemoglobin and the value of normal mean corpescular hemoglobin to calculate this-I can be wrong!

Answer 1

A typical human erythrocyte (red blood cell) contains about 270 million haemoglobin molecules, with each carrying four heme groups.

Decrease of hemoglobin, with or without an absolute decrease of red blood cells, leads to symptoms of anemia. Anemia has many different causes, although iron deficiency and its resultant iron deficiency anemia are the most common causes in the Western world. As absence of iron decreases heme synthesis, red blood cells in iron deficiency anemia are hypochromic (lacking the red hemoglobin pigment) and microcytic (smaller than normal).

The basic formula for hemoglobin was established by Zinofsky in 1885. He found that for each iron atom, the hemoglobin molecule contains 712 carbon, 1,130 hydrogen, 214 nitrogen, 243 oxygen, and 2 sulfur atoms.It have four irons in each molecule with a molecular weight of about 67,000. Ninety percent of the weight of a red blood cell is hemoglobin. There are approximately 300 million molecules of hemoglobin in each RBC; and, because one hemoglobin molecule contains four heme units, each erythrocyte can potentially carry more than a billion molecules of oxygen. Even though we speak of hemoglobin as a single substance, there are actually over 700 variants of the hemoglobin molecule

Answer 3

4 heme molecules

Answer 4

four.
