食用菌虎奶菇在三个不同生长阶段(包括菌丝、菌核和子实体)的细胞壁中均含有大量的超支化多糖。菌丝细胞壁中的多糖为杂多糖,分子量和粒径分别为4.502×104g/mol和33.2 nm,其主链由→1)-D-Glcp-(6→残基构成,并由部分→1)-D-Glcp-(4→和→1)-D-Glcp-(3→残基构成侧链,末端含有少量甘露糖、木糖和鼠李糖,分支度为45%。而菌核和子实体细胞壁多糖则主要由具有相似结构的超支化β-葡聚糖构成,该多糖主要由→1)-D-Glcp-(4→主链和→1)-D-Glcp-(6→侧链构成,并有少量→1)-D-Glcp-(3→存在于侧链中。主要分支位点在主链葡萄糖的O-3和/或O-6位,分支度为63%～70%。该类多糖分子量超过10g/mol,但粒径较小,仅为35 nm左右。进一步的结构分析发现,这类具有致密结构的超支化多糖具有类似支链淀粉的空间结构和内部空腔,在纳米载体、药物载运、新型材料等领域均具有巨大的潜在开发价值。

It is very difficult to make differences between hardware instrumentation and software instrumentation since through DSP (Digital Signal Processing) technology many deconvolution mathematical algorithms can be included into the instrumentation by Ic techniques to improve the instruments’ resolution. However, digital signal processing can always show some strange results due to noise sensitivity of inverse procedure, singular value problem, divergence problems, ring effects which make the deconvolution results difficult to explain. Further more, the limitation of the
