查询词典 ordered chain complex

The force is dominated by entropy force when the chain isdeformed less than 0.9 of the full-extended chain, while by enthalpy force. Theenthalpy force is contributed by the intro-molecular interaction. Bond stretchcontributes to the force more than bond angle bend. Torsion and VDW contributelittle to the force.3. The internal energy contribution to the elastic force It is in dispute that whether 〓 is dependent on the strain, and it is hard toresolve the problem using present elastic theories because they are athermal.

我们模拟了聚乙烯模型聚合物的SMFS，研究了链长、势能有效距离和温度对力谱的影响，探讨了力谱的本质问题，得到以下结果：改进的分子动力学方法可以很好的模拟聚合物的SMFS；SMFS是链段的性质而不是整个高分子链的性质，对于聚乙烯，该链段碳原子数目大于40；SMFS的本质是熵弹性，形变小于全伸直链的0.9时，力为熵弹力；形变超过全伸直链的0.9时，能弹力占主导地位，这种能弹力完全是分子内相互作用引起的，是由键伸缩和键角弯曲贡献的。3。

The results of pharmacological assays, together with the structural characterization of the derivatives, indicate that immunomodulatory activity of glucan derivatives not only depends on the glycosyl residue linkages and sugar chain conformation, but also is closely related to the nature of functional groups, degree of substitution and its distribution in a glycosyl residue and along the sugar chain.

These results, together with the structural elucidation of the purified polysaccharides described above, indicate that the α-glucans in G. lucidum don't have any remarkable immunomdulating activities, but the effects of β-glucans on immune system depend on their glycosyl residue linkages and sugar chain conformation. Further, it is concluded that the 1, 3-linked backbone, relative lower side chain size and substitution, and a high-organized helical structure are the beneficial structural features for the immunostimulatory activity of β-D-glucans. However, the 1, 6-linked backbone may induce the immunosuppressive effect of β-D-glucans.

结合各纯化多糖的结构与构象分析的结果，可以得出以下结论：赤灵芝中的α-型葡取糖不具有显著的免疫调节作用，而β-型葡聚糖的免疫作用则与其糖链结构和糖链构象有密切关系，1，3-连接的主链，较低的分支取代率和较短的支链长度及高度有序的螺旋结构是β-型葡聚糖发挥免疫增强功能的有利结构因素，相反，1，6-连接的主链却可能引起多糖的免疫抑制作用。

And physicochemical procedures (molecular weight measurement, viscosity analysis, etc.). All glycans (polysaccharides and peptidoglycan) were found as glucans, but each glucan has its specific sugar chain structure, including glycosyl reside linkages and sugar chain conformation.

结构研究表明，除PSG6为肽多糖以外，其他六个多糖均为由单一葡萄糖构成的葡聚糖，但各多糖在糖残基连接方式，糖苷键构型，支链的长度、取代度与在主链上的分布及糖链构象上有显著差异。
