Of the four globins that make up hemoglobin, two are identical and called alpha globins, and the other two are called beta globins and are also identical.

<h3>Structure of Haemoglobin</h3>
  • Each of the four subunits of hemoglobin has a polypeptide chain and a heme group.
  • The iron protoporphyrin IX prosthetic heme group, which is connected to a polypeptide chain with residues of 141 (alpha) and 146 (beta) amino acids, is present in all hemoglobins.
  • A histidine's N is linked to the ferrous iron of the heme. A polypeptide chain phenylalanine of the porphyrin ring wedges it into its pocket.
  • Alpha and beta chains, two varieties of the polypeptide chains that make up adult hemoglobin, are comparable in length but have different amino acid sequences.
  • Both adult and embryonic human hemoglobins have the same alpha chain.
