In biochemistry, receptor–ligand kinetics is a branch of chemical kinetics in which the kinetic species are defined by different non-covalent bindings and/or conformations of the molecules involved, which are denoted as receptor(s) and ligand(s). Receptor–ligand binding kinetics also involves the on- and off-rates of binding. A main goal of receptor–ligand kinetics is to determine the concentrations of the various kinetic … WebLigand + Receptor Ligand·Receptor The model is based on these simple ideas: • Binding occurs when ligand and receptor collide due to diffusion, and when the collision has the correct orientation and enough en-ergy. The rate of association (number of binding events per unit of time) equals [Ligand]⋅[Receptor]⋅kon, where kon is the association WebThink about receptor activation as involving 1) a specific ligand (e.g. morphine) binding its receptor AND 2) that binding inducing a shape change in the receptor.
