Cyclohexane-1,2-diol
Cyclohexane-1,2-diol is a chemical compound found in castoreum Castoreum is a yellowish exudate from the castor sacs of mature beavers. Beavers use castoreum in combination with urine to scent mark their territory. Both beaver sexes have a pair of castor sacs and a pair of anal glands, located in two cavities .... It can exist in either ''cis''- or ''trans''-isomers. The enzyme cyclohexane-1,2-diol dehydrogenase uses ''trans''-cyclohexane-1,2-diol and NAD+ to produce 2-hydroxycyclohexan-1-one, NADH and H+.

Cyclohexane-1,2-diol Dehydrogenase
In enzymology, a cyclohexane-1,2-diol dehydrogenase () is an enzyme that catalyzes the chemical reaction :trans-cyclohexane-1,2-diol + NAD+ \rightleftharpoons 2-hydroxycyclohexan-1-one + NADH + H+ Thus, the two substrates of this enzyme are trans-cyclohexane-1,2-diol and NAD+, whereas its 3 products are 2-hydroxycyclohexan-1-one, NADH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is trans-cyclohexane-1,2-diol:NAD+ 1-oxidoreductase. This enzyme participates in caprolactam degradation Caprolactam (CPL) is an organic compound with the formula (CH2)5C(O)NH. This colourless solid is a lactam (a cyclic amide) of caproic acid. Global demand for this compound is approximately five million tons per year, and the vast majority is used ....

Castoreum
Castoreum is a yellowish exudate from the castor sacs of mature beavers. Beavers use castoreum in combination with urine to scent mark their territory. Both beaver sexes have a pair of castor sacs and a pair of anal glands, located in two cavities under the skin between the pelvis and the base of the tail. The castor sacs are not true glands ( endocrine or exocrine) on a cellular level, hence references to these structures as preputial glands, castor glands, or scent glands are misnomers. It is used as a tincture in some perfumesInternational Perfume Museum, Grasse, France, Website: and was sometimes used as a food additive in the early 1900s. The sacs brought per ounce when auctioned at the May–June 2016 North American Fur Auction. Chemical composition At least 24 compounds are known constituents of beaver castoreum. Several of these have pheromonal activity, of which the phenols 4-ethylphenol and catechol and the ketones acetophenone and 3-hydroxyacetophenone were s ...

Cis–trans Isomerism
''Cis''–''trans'' isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. The prefixes "''cis''" and "''trans''" are from Latin: "this side of" and "the other side of", respectively. In the context of chemistry, ''cis'' indicates that the functional groups (substituents) are on the same side of some plane, while ''trans'' conveys that they are on opposing (transverse) sides. ''Cis''–''trans'' isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space. ''Cis-trans'' notation does not always correspond to E–Z notation, ''E''–''Z'' isomerism, which is an ''Absolute configuration, absolute'' stereochemical description. In general, ''cis''–''trans'' stereoisomers contain double bonds that do not rotate, or they may contain ring structures, where the rotation ...
