Biosynthesis of tetrahydrocannabinolic acid (THCA). In the first step, geranyl pyrophosphate and olivetolic acid form cannabigerolic acid, which is then enzymatically rearranged to THCA in the second step.

Cannabigerolic acid (CBGA) is the acidic form of cannabigerol (CBG). It is a dihydroxybenzoic acid and olivetolic acid in which the hydrogen at position 3 is substituted by a geranyl group. It is a biosynthetic precursor to Delta-9-tetrahydrocannabinol, which is the principal psychoactive constituent of the Cannabis plant. It is also a meroterpenoid (i.e. a polyketide and a terpenoid), a member of resorcinols and a phytocannabinoid. It derives from an olivetolic acid. It is a conjugate acid of a cannabigerolate.^[1]

In the Cannabis plant, olivetolic acid and geranyl diphosphate are synthesized into CBGA.^[2]^: 6^[3]^: 17 CBGA is converted in the plant by CBCA synthase, CBDA synthase and THCA synthase into CBCA, CBDA and THCA respectively.^[2]^: 6–7
