A new water-soluble lithium salt of thiazolidine-4-carboxylic acid was synthesized and characterized by chemical and spectroscopic techniques. Elemental and mass spectrometric (ESI-MS) analyses of the solid compound fit to the composition LiC(4)H(6)NSO(2). (1)H, (13)C nuclear magnetic resonance (NMR), [(1)H-(15)N] NMR
Journal of peptide science : an official publication of the European Peptide Society, 12(10), 621-625 (2006-06-21)
As proline plays an important role in biologically active peptides, many analogues of this residue have been developed to modulate the proportion of cis and trans conformers. A correlation between the pyrrolidine ring shape and structural properties of proline has
It is well established that L-proline has several roles in the biology of trypanosomatids. In Trypanosoma cruzi, the etiological agent of Chagas' disease, this amino acid is involved in energy metabolism, differentiation processes and resistance to osmotic stress. In this
