Dab tsi yog qhov feem pua enantiomeric tshaj ntawm qhov sib tov uas muaj 86?
Enantiomeric tshaj (ee): Qhov ntau tshaj ntawm ib qho enantiomer tshaj qhov sib tov ntawm enantiomers. Qhia lej: enantiomeric tshaj = % ntawm cov enantiomer loj - % ntawm cov me me enantiomer. Piv txwv li: Ib qho kev sib xyaw ua ke ntawm 86% R enantiomer thiab 14% S enantiomer muaj 86% - 14% = 72% ee
