Diabetic hemoglobin binding curve

WebHemoglobin is a tetramer composed of two each of two types of closely related subunits, alpha and beta. Myoglobin is a monomer (so it doesn't have a quaternary structure at all). Myoglobin binds oxygen more tightly … WebThe binding of oxygen to a heme group alters these intramolecular forces to increase affinity for oxygen on nearby heme groups. So, you can imagine in the lungs that oxygen is entering the blood and progressively increasing hemoglobin oxygen binding affinity (the flat part of the curve). This works the opposite as well.
