Qingbin Guo,Lianzhong Ai,Steve W. Cui classes. As a teacher, I find the chemistry with every class in my high school distinctive. I have noticed that while some students are positive about learning English, others appear rather timid. When they are asked to complete the questionnaire about their learning histories in the first class, t

Strategies for Structural Characterization of Polysaccharides,rides can be simply classified into four categories according to the source differences: plant polysaccharides, seaweed polysaccharides, animal polysaccharides and microbial polysaccharides (Table 1.1). Each category has its own specific structural features, e.g. most hemicelluloses as plant polysac

Polysaccharide Extraction and Fractionation,gum ghatti can be picked up directly from the tree bark (Kang, Guo, Phillips, & Cui, .). However, most of the non-starch polysaccharides need to be extracted by water, mild base or acid solution (Guo et al., ., .). Assisted methods such as heating, microwave, and sonication were also extensively use

1D & 2D and Solid-State NMR,havior in solution. Structural features including linkage patterns, configuration (α- or β-), sequencing as well as the ratio of different sugar residues all could be obtained. In addition, some conformational properties (molecular dynamics) of polysaccharides also are obtainable by this technique.
