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...
Half maximal inhibitory concentration (IC50) is a measure of the potency of a substance in inhibiting a specific biological or biochemical function. IC50 is a quantitative measure that indicates how much of a particular inhibitory substance (e.g....
The dose–response relationship, or exposure–response relationship describes the magnitude of the response of a biochemical or cell-based assay or an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after...
The Monod equation is a mathematical model for the growth of microorganisms. It is named for French biochemist Jacques Monod, who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration...
In pharmacology, the volume of distribution ( V D {\displaystyle V_{D}} , also known as apparent volume of distribution or volume of dilution) is the...
In the field of pharmacokinetics, the area under the curve (AUC) is the definite integral of the concentration of a drug in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry). In practice, the drug...
A logistic function or logistic curve is a common S-shaped curve (sigmoid curve) with the equation f ( x ) = L 1 + ...
Archibald Vivian Hill (26 September 1886 – 3 June 1977), better known to friends and colleagues as A. V. Hill, was a British physiologist, one of the founders of the diverse disciplines of biophysics and operations research. He shared the 1922 Nobel...
The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes. This model even explains the effect of pressure;...
