WebApr 13, 2024 · In addition to Hill coefficient γ, our final model also provides valuable insight on other target binding-related parameters, such as K H, the drug concentration that can occupy 50% of hemoglobin binding sites, and R tot, the capacity of the hemoglobin. WebQuick Reference. A coefficient devised by A. V. Hill (1886–1977) to describe the binding of oxygen to haemoglobin (Hill coefficient of 2.8) and used more generally as a measure of cooperativity in a binding process. A Hill coefficient of 1 indicates independent binding, a value greater than 1 indicates positive cooperativity in which binding ...
