Question: how is cbga converted into thca?
Answer: Cannabigerolic acid (CBGA), a precursor of THCA, is the product of the alkylation of olivetolic acid with geranyl pyrophosphate by an enzyme called geranylpyrophosphate:olivatolate geranyltransferase (Fellermeier and Zenk 1998). Then, CBGA is converted into THCA by a novel enzyme called THCA synthase (Taura et al.
