The pathogenic yeast Candida albicans produces large N-glycans with outer regions containing only mannose residues. The outer region comprises a primary branch with multiple secondary and tertiary branches. Tertiary branches are linked to secondary branches by phosphodiester bridges. In the current model of outer chain elongation in the genetically related yeast Saccharomyces cerevisiae, synthe...

Sporomorphs (pollen and spores) have an outer wall composed of sporopollenin. Sporopollenin chemistry contains both a signature of ambient ultraviolet-B flux and taxonomic information, but it is currently unknown how sensitive this is to standard palynological processing techniques. Oxidation in particular is known to cause physical degradation to sporomorphs, and it is expected that this shoul...

Acetolysis of dextran B-1299-S provides a preparative approach to crystalline u-kojibiose octaacetate. The latter was transformed via crystalline hepta-O-acetylct-kojibiosyl bromide into p-nitrophenyl and p-isothiocyanatophenyl /3-kojibiosides.
