Cannabis Compound Identification
Common NameDetla-8-tetrahydrocannabinolic acid
DescriptionDelta-8-tetrahydrocannabinolic acid, also known as Delta-8-THCA, belongs to the class of organic compounds known as 2,2-dimethyl-1-benzopyrans. Detla-8-tetrahydrocannabinolic acid is one of more than 120 cannabinoid compounds that are known in cannabis plant. It is one of the only two delta-8-THC-type cannabinoids in cannabis, namely delta-8-THC and delta-8-THCA. Delta-8-THC and its acid precursor are considered as THC and THC acid artifacts, respectively. The 8,9 double-bond position is thermodynamically more stable than the 9,10 position. Delta-8-THC is approximately 20% less active than THC (PMID: 6991645 ). THC acid is produced via the following pathway: Geranyl pyrophosphate and olivetolic acid react, catalyzed by an enzyme Geranyl-pyrophosphate—olivetolic acid geranyltransferase to produce cannabigerolic acid which is then cyclized by the enzyme THC acid synthase to give THC acid.
