| Abstract: | 13C-NMR spectral data are presented for four neuropeptides composed ofl-Asp, Ac-l-Asp, andd-Glu, which contain  and  peptide linkages. The data for the various compounds are compared to related dipeptides, one of which is a known neuropeptide, in order to gain structural information about these compounds. Electron-nuclear relaxation rates were used to elucidate the metal-ion binding sites of these species. |
