WebThe slope of the hill plot at the point of log(Y/(1-Y))= 0, the midpoint of binding is called the Hill Coefficient. Thus the Hill coefficient for myoglobin is 1. The Hill coefficient of 1 means that the oxygen atoms bind independently of each other. II Hemoglobin Hemoglobin (Hb) is a compact globular protein. WebThis value is determined from the slope of the hill plot (log 1 versus log pO 2). The fact that the Hill plot is linear with slope 1.0 is interpreted to mean that only one O 2 binds to … Web123 Fig. 1.UV-vis spectra of hemoglobin and myoglobin at pH 5-13.Arrows indicate trends in absorbance with increasing pH.

"WebMar 15, 2024 · This model implies what is described as infinitely cooperative binding of oxygen. (Notice that the Hill equation becomes: Y = L/ [K D + L], when n =1 (as in the case with myoglobin, and in any equilibrium expression of the form M+L↔ML. Remember plots of ML vs L or Y vs L gives hyperbolas, with K D = L at Y = 0.5.) " - Hill plot of myoglobin and hemoglobin
