Chemical compound
cis -3-Hexenal , also known as (Z )-3-hexenal and leaf aldehyde , is an organic compound with the formula CH3 CH2 CH=CHCH2 CHO. 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]
