cis-3-Hexenal, also known as (Z)-3-hexenal and leaf aldehyde, is an organic compound with the formula CH3CH2CH=CHCH2CHO. It is classified as an unsaturated aldehyde. It is a colorless liquid and an aroma compound with an intense odor of freshly cut grass and leaves.[1][2]
Occurrence
It is one of the major volatile compounds in ripe tomatoes, although it tends to isomerize into the conjugated trans-2-hexenal.[3] It is produced in small amounts by most plants and it acts as an attractant to many predatory insects. It is also a pheromone in many insect species.[4]
Biosynthesis of cis-3-hexenal from linolenic acid via the hydroperoxide by the action of a lipoxygenase followed by a hydroperoxide lyase.[5]
See also
- cis-3-hexen-1-ol has a similar but weaker odor and is used in flavors and perfumes.
- 1-Hexanol, another volatile organic compound, also considered responsible for the freshly mowed grass odor
