Metabolite Identification
Common Name(-)-Kaur-16-en-19-oic acid
Description(-)-kaur-16-en-19-oic acid, also known as ent-kaurenoic acid or ent-kaur-16-en-19-oate, is a member of the class of compounds known as kaurane diterpenoids. Kaurane diterpenoids are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D (-)-kaur-16-en-19-oic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). (-)-kaur-16-en-19-oic acid can be found in sugar apple and sunflower, which makes (-)-kaur-16-en-19-oic acid a potential biomarker for the consumption of these food products.
