WebEach of the acidic and basic amino acids contains an ionizable group in its side chain. Thus, both free and some of the combined amino acids in peptide linkages can act as buffers. The concentration of a weak acid (HA) and its conjugate base (A-) is described by the Henderson- Hasselbalch equation. fDerivation of the equation http://www.biology.arizona.edu/biochemistry/problem_sets/aa/Glycine.html
