Lipopolysaccharide (LPS) was isolated from Yersinia enterocolitica serovars O:10 and O:10 KL and the structural pattern of O-specific sugar chains elucidated.The rhamman and L-xylulose (L-threo-pent-2-ulose) as constituents of the O-specific polysaccharide were obtained by autohydrolysis of the LPS.The rhamman was shown to be a linear, α-(1->3)-linked polysaccharide in the D configuration.L-Xylulose was purified using paper chromatography on a preparative scale and its structure was confirmed by 13C NMR spectroscopy.Using sugar and methylation analysis and 13C NMR s pectroscopy of the LPS and the rhamman, the structural features of the disaccharide repeating unit of the Y. enterocolitica O:10 O-specific polysaccharide were elucidated as:-3)-(1-> Keywords: Yersinia enterocolitica; Lipopolysaccharide; O-Specific polysaccharide; D-Rhamman; L-Xylulose (L-threo-Pent-2-ulose)

Few nucleoside-derived natural products have been identified from animals, despite the ubiquity of nucleosides in living organisms. Here, we use a combination of synthesis and the emerging electron microscopy technique microcrystal electron diffraction to determine the structures of several N3-(β-glucopyranosyl)uric acid derivatives in Caenorhabditis elegans. These noncanonical gluconucleosides further integrate an ascaroside moiety, for which we present a shortened synthetic route. The production of a phosphorylated gluconucleoside is influenced by evolutionarily conserved insulin signaling.

The invention relates to 3,6-dideoxy-3-amino-L-idose having a structure shown as a following formula in the specification and synthetic method of its derivative. In the specification, R1 is H or a common glycosyl terminated protective group; R2 and R3 are respectively H or the common glycosyl terminated protective group; and R4 is H or the common glycosyl terminated protective group. According to the invention, L-rhamnose is taken as an initial raw material, the synthetic method is simple and efficient, compared with the prior art, the operation is simple, the overall yield is relatively high, metal having large toxicity can be avoided, in the final reduction step, and the different amino sugars can be respectively obtained by employing different reduction methods.
