How many molecules of Hemoglobin are there in ONE healthy normal red blood cell (RBC)?
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.
