  • We tend to think of haemoglobin as a single chemical substance but as we shall see in this Factsheet:

    • A haemoglobin molecule consists of subunits, each made up of a polypeptide chain and an iron-containing haem group.
    • Differences in the amino acids in the polypeptide chain result in different haemoglobins with different oxygen-transporting properties
    • Different organisms live in different environments with different oxygen availability. Their haemoglobin is adapted to the way of life of the organism concerned.
