characterize by conventional 1H nuclearmagneticresonance (NMR) approaches in solution. Here, we report a solid-state 17O NMR analysis of synthetic glucosamine with 17O enrichment at position 6. Based on magic-angle spinning and stationary spectral data obtained at varying magnetic fields in conjunction with quantum chemical calculations, we successfully estimated 17O chemical shift and electric field
碳水化合物的羟基是其构象动力学和分子间相互作用的关键决定因素,但很难通过溶液中的常规1 H核磁共振(NMR)方法进行表征。在此,我们报告了在6位富集17 O的合成氨基葡萄糖的固态17 O NMR分析。基于魔角旋转和在可变磁场下获得的固定光谱数据,结合量子化学计算,我们成功地估算了17 O化学位移和电场梯度张量,为寡糖结构的17 O NMR分析提供了基准。
