氨基酸结构分析?lz你是想用于鉴别还是什么?如果只是鉴别 可以测比旋光度 分析的话 用手性柱试试吧 Sorry for figuring out that u just mistake the concepts of D/L and (+)/(-). D/L conformation is not the same as (+)/(-). It is determined by the structure the chemical has, while (+)/(-) is tested by polarimeter. The materials with D conformation can be either (+)/(-), so u can get to know the optical rotation of a sample by polarimeter, but can't draw a conclusion that it is of D or L conformation,查看更多
