WebMay 8, 2024 · The Hill plot of actual Hb binding data is curvilinear, and cross the x axis only once. Howver, the ends of the curve (at low and high dioxygen) approach straight lines with slopes of 1 (i.e. n=1). If extrapolated through the x axis, these lines would give the Kd for the binding of the first and last dioxygens, which bind noncooperatvely. impact factor of powder technology

WebThe Hill coefficient, named for Archibald Vivian Hill, provides a way to quantify this effect. It describes the fraction of the macromolecule saturated by ligand as a function of the ligand concentration; it is used in determining the degree of cooperativeness of the ligand binding to the enzyme or receptor. WebThis variable is called the Hill slope, the slope factor, or the Hill coefficient. If it is positive, the curve increases as X increases. If it is negative, the curve decreases as X increases. A standard sigmoid dose-response curve (previous equation) has a Hill Slope of 1.0. When HillSlope is less than 1.0, the curve is more shallow.

You can have a Hill coefficient that is as large as the number of subunits available, though just because you have 4 subunits doesn't necessarily mean the coefficient is 4. Just that it can't be any higher than that. If binding to one subunit makes it harder for other subunits to bind, that's negative cooperativity.
