英文摘要: This work studied the self-assembling (crystallizing) behaviour of amino acids in the absence of solvent and additives (by sublimation and deposition in vacuum), instead of from aqueous solution. It is found that the hydrophilicity/hydrophobicity of side-chains can significantly affect the crystallization of amino acids in the absence of solvent. Crystal structures of amino acids having hydrophobic side-chains (L.-valine, L-leucine, L-isoleucine and L-methionine) obtained from sublimation are the same with those obtained from aqueous solution. New polymorphs for six amino acids are thought to have been obtained, based on X-ray diffraction and IR data for three of them (L-tyrosine, L-Phyenylalanine and L-tryptophan), and just IR data for the other three (L-alanine, L-proline and L-threonine).
