WebHemoglobin is a globular transport protein; however, the mutation in Hemoglobin S leads to a change in the globular nature of the protein due to the formation of polymers, which is a fibrous protein characteristic. Deoxyhemoglobin S is physiologically found in its polymerized structure in which hemoglobin tetramers bind in double stranded form. Hemoglobin has a quaternary structure characteristic of many multi-subunit globular proteins. Most of the amino acids in hemoglobin form alpha helices, and these helices are connected by short non-helical segments. Hydrogen bonds stabilize the helical sections inside this protein, causing attractions within the molecule, which then causes each polypeptide chain to fold into a specific … WebAug 10, 2024 · Haemoglobin is a tetramer composed of four subunits, two α and two β These subunits form two identidal αβ dimers Each subunit has a haem group The quaternary structure of haemoglobin is essential for positive cooperativity: Each time one of the monomers binds oxygen, the molecule of haemoglobin undergoes a conformational change pinpoint exmouth
