Hill type equation

WebHill-Langmuir equation This is the important Hill-Langmuir equation. A. V. Hill was the first (in 1909) to apply the law of mass action to the relationship between ligand concentration and receptor occupancy at equilibrium and to the rate at which this equilibrium is approached. The physical chemist I. Langmuir showed a few years later that a similar … WebJan 10, 2024 · A The Hill equation for cooperative protein–ligand interactions and sigmoidal curves with different degrees of cooperativity. S, a saturation value; EC 50, the ligand concentration to achieve half-maximum binding; h, the Hill coefficient indicating the degree of cooperativity.
