Best Answer: Haemoglobin is a protein and all proteins contain the elements Nitrogen, Hydrogen, Carbon and Oxygen only but Haemoglobin also contains Iron.emoglobin or haemoglobin is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. The molecule consists of globin, the apoprotein, and four haem groups, an organic molecule with an iron atom. Source(s): wikipedia. Ed F Â· 9 years ago.
One gram of haemoglobin contains 3.4 mg of iron. In a normal individual with 15 g of haemoglobin per dl, 100 ml of blood contains approximately 50 mg of iron. Thus removal of only 2 ml of blood results in the loss of 1 mg of iron3. If 450 ml of blood are taken in a donation approximately 225 mg of iron will be lost. If the donor has no iron deficiency, the erythrocytes and the haemoglobin level will generally return to normal within 34 weeks.
