WebDec 22, 2024 · Thus the slope of the Hill equation is simply n . This is called the Hill coefficient or n H . For myoglobin, its value is 1 because myoglobin does not bind cooperatively to O 2. For HbA, however, it is 2.8. The higher the n H , the more sigmoidal the kinetics of the reaction under study.

WebHill plots of myoglobin and hemoglobin The graph for myoglobin (Mb) gives a straight line with the expected Hill coefficient n H = 1. For hemoglobin n H = 2.8 in the range 1 kPa to 100 kPa.
