In enzymology, a cinnamyl-alcohol dehydrogenase (EC 1.1.1.195) is an enzyme that catalyzes the chemical reaction. cinnamyl alcohol + NADP + cinnamaldehyde + NADPH + H +. Thus, the two substrates of this enzyme are cinnamyl alcohol and NADP +, whereas its 3 products are cinnamaldehyde, NADPH, and H +.
The commercial material often contains low levels of 2,6-di-tert-butyl-4-methoxyphenol as a stabilizer. It is a derivative of cinnamaldehyde with a hexyl substituent. One supplier reported that its hexyl cinnamaldehyde (or "hexyl cinnamic aldehyde") contained at least 90% trans isomer. [2]
Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
Cinnamoyl-CoA reductase (EC 1.2.1.44), systematically named cinnamaldehyde:NADP+ oxidoreductase (CoA-cinnamoylating) but commonly referred to by the acronym CCR, is an enzyme that catalyzes the reduction of a substituted cinnamoyl-CoA to its corresponding cinnamaldehyde, utilizing NADPH and H + and releasing free CoA and NADP + in the process.

The European Parliament registered cinnamyl acetate as both a flavouring substance and a cosmetic compound in 1996. [14] [15] The Joint (FAO/WHO) Expert Committee on Food Additives described in 2000 that “the substance does not present a safety concern at current levels of intake when used as a flavouring agent”.
