(如图所示)转向：葡萄糖和甲基乙炔基吡啶聚合物在甲醇水溶液中形成的络合物的首选螺旋感觉通过突变反转(见图)。由纯α-和β-D-葡萄糖引起的强圆二色谱效应随时间减弱，这是因为通过突变减少了非对映异构体过剩。椭圆度的转变曲线与异常率的转变曲线密切相关。
(Figure Presented) About turn: The preferred helical sense of the complex formed between glucose and the meto-ethynylpyridine polymer in aqueous methanol is inverted by mutarotation (see picture). The strong circular dichroism effects induced by pure α-and β-D-glucose weakened with time because the diastereomer excess decreased through mutarotation. The transition curve of the ellipticity closely reflected that of the anomer ratio.
