Hill type function

In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that forms a complex with a biomolecule to serve a biological purpose" (ligand definition), and … See more The Hill–Langmuir equation is a special case of a rectangular hyperbola and is commonly expressed in the following ways. , where: See more The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, $${\displaystyle n}$$ or • See more The Hill and Hill–Langmuir equations are used extensively in pharmacology to quantify the functional parameters of a drug and are also used in other areas of biochemistry. See more • Binding coefficient • Bjerrum plot • Cooperative binding • Gompertz curve • Langmuir adsorption model See more The Hill-Langmuir equation is derived similarly to the Michaelis Menten equation but incorporates the Hill coefficient. Consider a protein (), … See more Because of its assumption that ligand molecules bind to a receptor simultaneously, the Hill–Langmuir equation has been criticized as a physically unrealistic model.
