| Common Name | (E,Z)-2,4-Heptadienal |
|---|
| Description | (E,Z)-2,4-Heptadienal belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, (e,Z)-2,4-heptadienal is considered to be a fatty aldehyde lipid molecule (E,Z)-2,4-Heptadienal is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (E,Z)-2,4-Heptadienal is a cinnamon and hazelnut tasting compound. Outside of the human body, (E,Z)-2,4-Heptadienal is found, on average, in the highest concentration within kohlrabis (E,Z)-2,4-Heptadienal has also been detected, but not quantified in, cauliflowers. This could make (e,Z)-2,4-heptadienal a potential biomarker for the consumption of these foods. |
