| Common Name | Octa-trans-3-cis-5-dien-2-one |
|---|
| Description | Octa-trans-3-cis-5-dien-2-one, also known as (e,z)-3,5-octadien-2-one, is a member of the class of compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR'. Octa-trans-3-cis-5-dien-2-one is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Octa-trans-3-cis-5-dien-2-one can be found in tea, which makes octa-trans-3-cis-5-dien-2-one a potential biomarker for the consumption of this food product. |
