Koj tuaj yeem txheeb xyuas seb ob lub molecules puas yog enantiomers (lossis tsis yog) yooj yim los ntawm kev tshuaj xyuas lawv cov npe thiab lawv cov npe (R, S) ! Tam sim no, yuav ua li cas yog tias peb muaj molecule nrog tib lub npe, tsuas yog lawv (R, S) lub npe tsis txawv, tab sis tsis zoo ib yam? Zoo li (R, R) thiab (R, S)…. los yog (S, S) thiab (S, R) ?
Koj paub li cas yog cov tebchaw yog enantiomers?
Molecules uas yog daim iav duab tab sis tsis yog superimposable yog enantiomers. Yog tias lawv tsis yog superimposable, thiab lawv tsis yog daim iav duab, ces lawv yog diastereomers.
Cov piv txwv ntawm enantiomers yog dab tsi?
1: Enantiomers: D-alanine thiab L-alanine yog cov piv txwv ntawm enantiomers lossis iav duab. Tsuas yog L-forms ntawm amino acids yog siv los ua cov proteins. Organic compounds uas muaj cov chiral carbon feem ntau muaj ob yam uas tsis yog superposable.
Koj tuaj yeem paub qhov txawv ntawm tus enantiomer los ntawm tus qauv li cas?
Enantiomers txawv tsuas yog hauv lawv qhov kev ua haujlwm kho qhov muag xws li qhov kev taw qhia uas lawv tig lub dav hlau polarized teeb. Yog hais tias ib tug enantiomer tig lub teeb polarized mus rau sab xis los yog nyob rau hauv ib tug clockwise kev taw qhia, nws yog hais tias yog tus (+) los yog lub dextrorotatory isomer.
Enantiomers 12 piv txwv yog dab tsi?
Ib qho piv txwv ntawm ib khub ntawm enantiomers yog dextro lactic acid thiab laevo lactic acid, uas nws cov qauv tshuaj tau piav qhia hauv qab no.
