WebOct 5, 2016 · While myoglobin, as a monomeric oxygen-binding protein, is presumably limited to hyperbolic saturation, oxygen binds cooperatively to hemoglobin. This gives rise to a sigmoidal form to the oxygen saturation curve for hemoglobin. A simple, elegant model for the sigmoidal binding curve is the symmetry or Monod-Wyman-Changeux (MWC) model .

"WebFor oxygen binding proteins the KD is also referred to as the “p50”, the amount of oxygen required to give a fractional saturation of Y=0.5. In the case of myoglobin, the KD is 2-3 torr. This rather strange binding behavior for the hemoglobin binding curve is due entirely to the fact that it can bind oxygen in a cooperative fashion. " - Myoglobin cooperative binding
