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 ... WebThe Hill equation is an equation used in biochemical characterization. In biochemistry, the binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as cooperative binding). The Hill coefficient, named for Archibald Vivian Hill, provides a way to quantify this ...

WebC The Hill Coefficient A traditional measure of cooperative interaction among the binding sites within a protein is the Hill coefficient nH = d ln ln x, which is usually determined as the slope of a logarithmically transformed binding curve (cf. Gutfreund and Edsall, 1978; Wyman and Gill, 1990 ). WebThe steepness is quantified by the Hill slope, also called a slope factor. A dose-response curve with a standard slope has a Hill slope of 1.0. A steeper curve has a higher slope factor, and a shallower curve has a lower slope factor.
