WebFor accurate measurements of binding affinity, the curve of the thermogram must be sigmoidal. The profile of the curve is determined by the c-value, which is calculated using the equation: where is the stoichiometry of the binding, is the association constant and is the concentration of the molecule in the cell. Binding curves showing the characteristically sigmoidal curves generated by using the Hill–Langmuir equation to model cooperative binding. Each curve corresponds to a different Hill coefficient, labeled to the curve's right. The vertical axis displays the proportion of the total number of receptors that have been … See more 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 … See more The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, 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.
