"WebSep 4, 2024 · In biochemistry, KD refers to the dissociation constant. It is a type of equilibrium constant that measures the propensity of the dissociation of a complex molecule into its subcomponents. It describes how tightly a ligand binds to a particular protein, or at which point the salt dissociates into its component ions. What does high Kd mean? " - Binding constants kd
