Oxalobacteraceae科細菌が生成する新規吸水性多糖由来オリゴ糖のNMR解析

抄録

  Partial acid hydrolysis of a new water-absorbing polysaccharide (WAP) from the family Oxalobacteraceae gave six di-, four tri-, two tetra-, two penta-, and one hexasaccharides composed of mannose, glucose, and/or galactose. The structures of oligosaccharides 1-15 were elucidated by extensive 2D NMR spectroscopic analyses. ¹H- and ¹³C-NMR chemical shift assignments of oligosaccharides 1-14 are presented.
