Partial Acid Hydrolysis and Molecular Degradation,Polysaccharides are generally degraded into oligosaccharides prior to their structural characterization, while the degradation methods can be classified into two big categories, non-specific degradation and controlled specific degradation.

MALDI-TOF-MS for Polysaccharides Analysis,Mass spectroscopy has been widely applied for carbohydrate analysis in terms of molecular mass, constituent monosaccharides, linkage types, sequencing of sugar residues, branching features, types of modifying groups, and the quantity.

Detailed Experimental Procedures,Weigh 10 mg polysaccharide sample, adding 1 mL 12 M sulphate acid and keep stirring at room temperature for 30 min until sample dissolved well. Dilute the solution accordingly, normally 10 times and waiting for test.

Monosaccharide Composition Analysis,al information. For example, polysaccharides containing arabinose and xylose are mostly assigned to arabinoxylan family; polysaccharides composed of galactose and mannose mostly belong to galactomannan group; pectic polysaccharides are mostly constructed by galacturonic acid and some neutral monosaccharides.

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.

Summary,d, the structure investigation of polysaccharides can only be termed as structural characterization rather than molecular sequencing due to the complexity and irregularity of the molecular chain. The obtained molecular structure can only be referred as “the proposed structure”.

s more than two independent parameters. On the other hand, if the training set includes fewer parameter samples, the greedy algorithm might produce a reduced-order model with large errors at the samples outside of the training set. We introduce a method based on a surrogate error model to efficientl
