Structure elucidation of the core octasaccharide from Citrobacter PCM 1487 with the aid of 500-MHz, two-dimensional phase-sensitive correlated, relayed-coherence transfer, double-quantum, triple-quantum filtered, and N.O.E. H-n.m.r. spectra |

Abstract: | The main features of the primary structure of the octasaccharide, -
-Glcp-(1→2)- -
-Glcp-(1→2)- -
-GalpNAc- (1→3)]- -
-Galp-(1→3)- -
-Glcp-(1→3)- -
-Hepp-(1→7)]- -
-Hepp-(1→3)- -
-Hep, have been determined in the ab initio manner by 1H-n.m.r. spectroscopy without resorting to biochemical methods of analysis. Several nontypical interresidue n.O.e. values point to a preferred solution conformation of the molecule. |
