[(alpha-L-fucopyranosyl)-(1-->2)]-O-(beta-D-galactopyranosyl)-(1-->3)-O- (2-acetamido-2-deoxy-alpha-D-galactopyranosyl)-(1-->3)-L-serine, a core I glycotetraosyl peptide structure and a predominant substructure in complex glycan-glycoproteins present in human bloodgroup A ovarianmucin, was synthesized for the first time. The title compound was synthetically accomplished via the following key manoeuvres: regio- and

Synthetic ligand compounds and methods of differentiating between Shiga toxin 1 and Shiga toxin 2 are disclosed herein. Another embodiment includes a kit for differentiating between Shiga toxin 1 and Shiga toxin 2. Assay systems and methods for providing an assay are also provided for herein.
The isolation, structuraldetermination, and chemical synthesis of an N-glycan from the hyper-thermophilic archaeon Thermococcus kodakarensis are reported. The identified N-glycan possesses a highly glycosylated myo-inositol moiety, which is linked to a disaccharide unit through a phosphodiester. Although myo-inositol is ubiquitous in archaea and eukaryotes, inositol-containing N-glycans were unknown
The synthesis of beta-Gal-(1 -> 3)-alpha-GalNAc-(1 -> 3)-beta-GalNAc allyl trisaccharide as the outer core fragment of Burkholderia cepacia pv. vietnamiensis lipooligosaccharide was accomplished through a concise, optimized, multi-step synthesis, having as key steps three glycosylations, that were in-depth studied performing them under several conditions. The target trisaccharide was designed with an allyl aglycone in order to open a future access to the conjugation with an immunogenic protein en route to the development of a synthetic neoglycoconjugate vaccine against this Burkholderia pathogen.
