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. 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. Moreover, the Hill coefficient should not be considered a reliable … 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-Langmuir equation is derived similarly to the Michaelis Menten equation but incorporates the Hill coefficient.

WebA sigmoidal curve shows that oxygen binding is cooperative; that is, when one site binds oxygen, the probability that the remaining unoccupied sites that will bind to oxygen will increase. The importance of cooperative behavior is that it allows hemoglobin to be more efficient in transporting oxygen. Why is allosteric enzyme sigmoidal curve?
