  2. Dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Dissociation_constant

    In chemistry, biochemistry, and pharmacology, a dissociation constant (K D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.

  3. Dissociation (chemistry) - Wikipedia

    is equal to the ratio of the dissociation rate of the ligand-receptor complex to its association rate (=). [8] Kd is the equilibrium constant for dissociation. K A {\textstyle K_{A}} is defined so that ( K A ) n = K d = k d k a {\textstyle (K_{A})^{n}=K_{\rm {d}}={k_{\rm {d}} \over k_{\rm {a}}}} , this is also known as the microscopic ...

    In chemistry and biochemistry, the Henderson–Hasselbalch equation = + ⁡ ([] []) relates the pH of a chemical solution of a weak acid to the numerical value of the acid dissociation constant, K a, of acid and the ratio of the concentrations, [] [] of the acid and its conjugate base in an equilibrium.

  7. Binding constant - Wikipedia

    en.wikipedia.org/wiki/Binding_constant

    The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, [1] and is the inverse of the dissociation constant. [2] It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as: R + L ⇌ RL

  8. Dissociation rate - Wikipedia

    en.wikipedia.org/wiki/Dissociation_rate

    Substrate dissociation rate contributes to how large or small the enzyme velocity will be. [2] In the Michaelis-Menten model, the enzyme binds to the substrate yielding an enzyme substrate complex, which can either go backwards by dissociating or go forward by forming a product. [2] The dissociation rate constant is defined using K off. [2]
