It also occurs to the extent of about 40–60% in dill seed oil (from Anethum graveolens), and also in mandarin orange peel oil. R-(−)-Carvone is also the most abundant compound in the essential oil from several species of mint, particularly spearmint oil (Mentha spicata), which is composed of 50–80% R-(−)-carvone. [9]
DEXRON-ULV is composed of a Group 3+ base oil and additives needed for the proper operation of the 2017 and above GM 10L90 and the Ford 10R80 10-Speed rear-wheel-drive automatic transmission. This transmission and the transmission fluid specification were co-developed by Ford and GM.
The dehydrogenation of carvone with a palladium-carbon catalyst has been established. [5] It has also been prepared by transalkylation of isopropylated cresols. [19] It is extracted from Origanum oil by means of a 50% potash solution. It is a thick oil that sets at -20 °C to a mass of crystals of melting point 0 °C, and boiling point 236 ...
There is no strict relationship between the R/S, the D/L, and (+)/(−) designations, although some correlations exist. For example, of the naturally occurring amino acids, all are L, and most are (S). For some molecules the (R)-enantiomer is the dextrorotary (+) enantiomer, and in other cases it is the levorotary (−) enantiomer. The ...
Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "l" (for "levo") and "d" (for "dextro"). The l isomer is the one most often encountered: it occurs naturally in many foods, and is one form ("vitamer") of vitamin C, an essential nutrient for humans and many animals.
Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction.The terms are derived from the Latin words for "left" (sinister) and "right" (dexter).

For example, sabinene contributes to the spicy taste of black pepper, 3-carene gives cannabis an earthy taste and smell, citral has a lemon-like pleasant odor and contributes to the distinctive smell of citrus fruits, and thujene and carvacrol are responsible for the pungent flavors of summer savory and oregano, respectively.
