Carvone ua ob daim iav duab daim ntawv los yog enantiomers: R -(–)- carvone los yog L- carvone , muaj ib tug sweetish mint tsw, zoo li spearmint nplooj. Nws daim iav iav, S -(+)- carvone , los yog D- carvone , muaj ntsim aroma nrog sau ntawv ntawm rye, zoo li caraway noob.

Yog li ntawd, R Carvone yog dab tsi?

Nqe lus piav qhia: (-)- carvone yog a carvone muaj ( R ) configuration. Nws yog ib tug enantiomer ntawm ib tug (+)- carvone . CEEB. (S)-2-methyl-5-(1-Methylethenyl)-2-cyclohexen-1-one belongs rau chav kawm ntawm cov organic tebchaw hu ua menthane monoterpenoids.

Tsis tas li ntawd, Carvone puas yog ketone? Carvone (Fig. 11.2) yog ib qho tseem ceeb heev monoterpene ketone lub cev rau kev lag luam tsw. S-(+)- Carvone yog cov khoom tseem ceeb ntawm caraway roj thiab dill, nrog ib qho tsw zoo li cov tshuaj ntsuab no.

Tib neeg kuj nug, vim li cas R thiab S carvone tsw txawv?

Daim duab 2: R thiab S enantiomers ntawm carvone . Lub chirality ntawm carvone yog txhais ncaj qha rau hauv qhov tsis sib xws hauv tsw vim hais tias ob peb olfactory receptors nyob rau hauv koj lub qhov ntswg yog chiral thiab yuav sau npe rau tej yam enantiomers muaj zog tshaj lwm tus. Yog li ntawd, ( R ) carvone tsw zoo li spearmint thiab ( S ) carvone tsw zoo li caraway.
