pka is the negative log base ten of the ka value (acid dissociation constant). it measures the strength of an acid. the lower the value of pka, the stronger the acid and the greater its ability to donate its protons. q3 what is ph full form? the letters ph stand for potential of ...

pK(a) values of ionizable residues have been calculated using the PROPKA method and structures of 75 protein-protein complexes and their corresponding free forms. These pK(a) values were used to compute changes in protonation state of individual residues, net changes in protonation state of the...
