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
Dab tsi yog qhov muaj pes tsawg leeg ntawm txhua txheej ntawm lub ntiaj teb?
Lub ntiaj teb tuaj yeem muab faib ua peb txheej tseem ceeb: lub hauv paus, lub mantle thiab crust. Txhua txheej ntawm cov khaubncaws sab nraud povtseg tuaj yeem muab faib ua ob ntu: sab hauv thiab sab nraud, sab sauv thiab sab hauv qab thiab sab av loj thiab dej hiav txwv crust. Ob qho tib si sab hauv thiab sab nraud yog tsim los ntawm cov hlau feem ntau thiab me ntsis ntawm nickel
