This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Experimental data, NMR, is available which shows that Neu5Ac and Neu5Gc have different 3D conformations. Aside from chemical differences between Neu5Ac and Neu5Gc, these 3D structural differences may also provide a mechanism for differences in biological recognition. Various polymers of Neu5Ac and Neu5Gc will be compared using Molecular Dynamics (MD) simulations to determine the 3D shapes of the polymers and comparisons will be made to experimental data of identical polymer lengths. Additionally, polymers without experimental data will be studied to provide predictive data for future experimental comparisons.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其他NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 实验数据（核磁共振）表明Neu 5Ac和Neu 5Gc具有不同的3D构象。 除了Neu 5Ac和Neu 5Gc之间的化学差异之外，这些3D结构差异也可能提供生物识别差异的机制。 将使用分子动力学（MD）模拟来比较Neu 5Ac和Neu 5Gc的各种聚合物，以确定聚合物的3D形状，并且将与相同聚合物长度的实验数据进行比较。 此外，没有实验数据的聚合物将进行研究，为未来的实验比较提供预测数据。
