Here is the chemical structure of carvone in 2D: But there is a topic in organic chemistry that has been the demise of many pre-meds - stereochemistry, which exists because carbon, the element which makes organic chemicals organic, always has four bonds, either to itself or other atoms.
Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments.
Structures of (4 S)- (+)-carvone (104′) and (4 R)- (−)-carvone (104). Carvone occurs as (+)-carvone (104), (−)-carvone (104′) (Scheme 103), or racemic carvone. (S)- (+)-Carvone (104) is the major component of caraway oil (∼60%) and dill oil and has a herbaceous odor reminiscent of caraway and dill seeds. In the case of carvone, it is clear that there is one asymmetric carbon atom (Figure 2). So there are two enantiomers, both found in nature, that are mirror images of each other.

I don't understand why this is a chiral carbon, to my understanding a chiral carbon is a carbon with 4 different chemical groups attached to it. In the molecule, the chiral carbon is surrounded by H, C (C H X 3) = C H X 2 and two C H X 2 groups. Carvone is a monoterpene present in caraway seeds, dill, and fennel fruits. These are mostly used as a folk remedy for diarrhea, acidity, and other gastric disorders. Carvone has a variety of pharmacological effects such as being an antioxidant, antinociceptive, insecticidal, anticancer, and having blood lipid lowering activity. Chemsrc provides L(-)-Carvone(CAS#:6485-40-1) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Articles of L(-)-Carvone are included as well.

Ginkgolide B (below) is a secondary metabolite of the ginkgo tree, extracts of which are used in Chinese medicine. Metabolic pathways for carvone in humans including oxidation of the double bond in the side chain and, to a minor extent 1,2- and 1,4 + 1,2-reduction of carvone, are discussed.

Plant material containing carvone may have been used for millenia, not pure carvone. 220.127.116.11 ( talk ) 21:23, 28 June 2009 (UTC) Assessment comment [ edit ] Note that (+)-carvone is the same thing as (S)-carvone. The (+) designation is based on its positive optical rotation value, which is experimentally measured.
