Description | Kaurenoic acid, also known as kaurenoate, belongs to the class of organic compounds known as kaurane diterpenoids. These 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. Kaurenoic acid is a weakly acidic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). (1r,4r,5s,9r,10s,13r)-5,9-dimethyl-14-methylidenetetracyclo[11.2.1.01,10.04,9]hexadecane-5-carboxylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (1R,4R,5S,9R,10S,13R)-5,9-Dimethyl-14-methylidenetetracyclo[11.2.1.01,10.04,9]hexadecane-5-carboxylic acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
