The formation of a ligand-protein complex LP {\displaystyle {{\ce {LP}}}} can be described by a two-state process L + P ↽ − − ⇀ LP {\displaystyle {\ce {L + P <=> LP}}} the corresponding dissociation constant is defined K d = {\displaystyle K_{d}={\frac {\left\left}{\left}}} where , {\displaystyle {\ce {, }}} and {\displaystyle {{\ce {}}}} represent molar concentrations of the protein, ligand and complex, respectively.
A formación dun complexo ligando-proteína LP {\displaystyle {{\ce {LP}}}} pode describirse como un proceso con dous estados L + P ↽ − − ⇀ LP {\displaystyle {\ce {{L}+ {P}<=> {LP}}}} a constante de disociación correspondente defínese como K d = {\displaystyle K_{d}={\frac {\left\left}{\left}}} onde , {\displaystyle {\ce {, }}} e {\displaystyle {{\ce {}}}} representan as concentracións molares da proteína, o ligando e o complexo, respectivamente.
