No significant change is shown in specific optical rotation, indicating the helical content of the BSA molecule remains unaltered. BSA经NBS处理后此旋光度无变化,说明螺旋程度未发生明显的改变。
Hydrogen bonds in non-helical arrangement in the insulin molecule 胰岛素分子中的非螺旋氢键
By treating with 2% Triton X-100 the mobility of bR molecule could be greatly increased. The characteristic of the ESR spectra showed that correlated with a partial loss of α-helical structure and changes in form of motion of bR molecule. 用2%TritonX&100处理可大大增加bR分子的‘柔性’,其ESR波谱特征与bR分子失去部分α螺旋结构和改变了它的某些运动方式有关。
