WebDec 29, 2024 · Dissociation constant (K d ) is the rate constant of dissociation at equilibrium, defined as the ratio k off / k on. Association constant (k a or K a ) is the opposite of K d. When K a is high, K d is low, and the drug has a high affinity for the receptor (fewer molecules are required to bind 50% of the receptors) Affinity in chemistry … WebBinding constants representing bisphosphonate affinity for human bone have been calculated by using several different methodologies. The direct binding affinity of alendronate for human bone was measured by Scatchard analysis, with a measured K d of 110 μM ( Leu et al. , 2006 ).
