Langmuir-Freundlich model Fitting in OriginLab (1 isotherm)

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 a macromolecule is a very large molecule, such as a protein, with a complex stru… WebThis equation is formally equivalent to the Langmuir isotherm.
