Web3.2 Dissociation rate constant k off. The dissociation rate constant allows the calculation of the time during which a reversible proteinase/inhibitor complex remains undissociated in vivo in the presence of a dissociating agent ( e.g. a biological substrate). Since complex dissociation is a first-order process, t 1/2, the half-life time of ...
Web1 represents the rate constant of dissociation of acetic acid to acetate and hydrogen ions, and k 2 represents the rate constant for the association of acetate and hydrogen ions to form acetic acid. The rate of dissociation of acetic acid, d[CH 3 COOH]/dt, is dependent on the rate constant of dissociation (k 1) and the concentration of acetic ...

WebDec 31, 2024 · In biochemistry and pharmacology, a variety of parameters are reported as measures of the potency of enzyme inhibitors/drugs, including Ki, Kd, IC50, and EC50. ... The Ki inhibition constant also represents a dissociation constant, but more narrowly for the binding of an inhibitor to an enzyme. That is, a ligand whose binding reduces the ...
WebKa = [A – ] [H + ]/ [HA] The reaction and definition can then be written in a more straightforward manner. pKa = – log10Ka. It is more convenient to discuss the logarithmic constant, pKa, for many practical uses. The relationship between Ka, pKa, and acid strength is as follows: the lower the Ka value, the higher the pKa value, and the ...
