Stability constants for the proton and metal ion complexation equilibria of aliphatic amino acids including α-alanine, valine, 2-aminopentanoic acid, leucine, isoleucine, 2-aminohexanoic acid and β-alanine were collected and critically evaluated. Data evaluation criteria involved the specification of the essential reaction conditions, the correctness of calibration techniques and calculation and the applicability of the methods used for the determination of stability constants. Recommended values for the proton and some metal ion complexes are collected in separate tables. Enthalpy values published on the protonation equlibria and metal ion complex formation processes of aliphatic amino acids were also surveyed.
