Binding constant
WebKinetics of Calcium and Magnesium Binding. The dissociation constant is the ratio of the off rate to the on rate: K d (M) = k off (s −1)/k on (M −1 s −1). The rate limiting dehydration of Ca (H 2 O) 7 21 is fast, ~10 8.0 s −1; while that of Mg (H 2 O) 6 21 is slow, ~10 4.6 s −1. This difference reflects the loose pentagonal ... 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…
