Bjellqvist et al. report a nearly complete set of amino acid pK values as part of their work in analyzing 2D gel electrophoresis (1). The pK values they report are pK values for the amino acids in polypeptides in 9.8 M urea at 25 oC. The pK values reported here are based on measurements and calculations from a variety of other studies (2-6).
