The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, and is the inverse of the dissociation constant. It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as: R + L ⇌ RL The reaction is characterized by the on-rate constant kon and the off-rate constant koff, which h… http://holford.fmhs.auckland.ac.nz/teaching/medsci719/workshops/ligandbinding/
