Department of Applied Chemistry, Delhi College of Engineering (University of Delhi), Delhi-110 006 Department of Chemistry, Ramjas College, (University of Delhi), Delhi-110 007 Manuscript received 7 April 1994, revised I April 1996. accepted 13 July 1996 The solubility of amino acids have been compiled at different temperatures to understand the thermodynamics of transfer of amino acids in· going from water to various solvent systems and interpreted in terms of solute-solvent interactions and structural changes of the amino acids in solvent mixture. A variety of solubility determination methods have been presented systematically. The order of solubility seems to be a function of specific solute-solvent interactions with non-polar portions of the amino acid molecules. The paper presents a review of advancements in thermodynamic behaviour of amino acids in various solvent (pure/mixed) systems
