摘要：
A calorimetic study, in the liquid phase, of the behaviour of some a-amino acids, which differ from each other in only the presence of heteroatom or in the position of the same heteroatom in their aliphatic side chains, is presented. The influence of the different electronegativity of the heteroatom explains how a small variation in the side chain can lead to large variations in the enthalpy values of the first, second and third ionization processes.
