Binding constant calculation
WebBinding affinity is typically measured and reported by the equilibrium dissociation constant (K D ), which is used to evaluate and rank order strengths of bimolecular interactions. The smaller the K D value, the greater the binding affinity of the ligand for its target. The larger the K D value, the more weakly the target molecule and ligand ... 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…
