Carvone forms two mirror image forms or enantiomers: S-(+)-carvone smells like caraway.Its mirror image, R-(–)-carvone, smells like spearmint. The fact that the two enantiomers are perceived as smelling differently is proof that olfactory receptors must contain chiral groups, allowing them to respond more strongly to one enantiomer than to the other.

Molecular Weight: 150.22. (-)-Carvone is a monoterpene ketone found in spearmint (Mentha spicata var. crispa) essential oil that is widely used as an odor and flavor additive. An intestinal antispasmodic effect was recently reported for (-)-carvone, and it has been shown to be more potent than its (+)-antipode.
