Figure 2. Molecular graphs for the conjugate bases of
methyl-pentose sugars. L-fucose deprotonated at
C4-HO4 (d) and L-rhamnose deprotonated
at C2-HO2 (f) show C-H…O
intramolecular H-bonds. Other conjugate baeses of methyl-pentose sugars
indicate O-H…O intramolecular H-bonds. The H-bonds in the
conjugate basese of methyl-pentose sugars are conventional (normal).
Small red spheres and lines correspond to the BCPs and bond paths,
respectively. |
