多糖結(jié)構(gòu)分析方法還是以單糖鑒定+波譜分析為主,尤其是多種NMR技術(shù)聯(lián)合。我就不詳細(xì)闡述了,給您一篇綜述文獻(xiàn)看看。 A review of NMR analysis in polysaccharide structure and conformation: Progress, challenge and perspective Abstract Nuclear magnetic resonance (NMR) has been widely used as an analytical chemistry technique to investigate the molecular structure and conformation of polysaccharides. Combined with 1D spectra, chemical shifts and coupling constants in both homo- and heteronuclear 2D NMR spectra are able to infer the linkage and sequence of sugar residues. Besides, NMR has also been applied in conformation, quantitative analysis, cell wall in situ, degradation, polysaccharide mixture interaction analysis, as well as carbohydrates impurities profiling. This review summarizes the principle and development of NMR in polysaccharides analysis, and provides NMR spectra data collections of some common polysaccharides. It will help to promote the application of NMR in complex polysaccharides of biochemical interest, and provide valuable information on commercial polysaccharide products. 下載地址 https://doi.org/10.1016/j.foodres.2021.110290 |
