Tetrahydrocannabinolic acid (THCA) synthase (full name Δ 1-tetrahydrocannabinolic acid synthase) is an enzyme responsible for catalyzing the formation of THCA from cannabigerolic acid (CBGA). THCA is the direct precursor of tetrahydrocannabinol (THC) , the principal psychoactive component of cannabis , which is produced from various strains of ...
Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis. [1]THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.
Cannabinoids, including tetrahydrocannabinol (THC), the active drug in cannabis, can also be produced by bioengineered yeast, a process colloquially known as pharming. [1] In 2007, a research group reported the successful transgenic placement of a THCA synthase gene from Cannabis plant into the Pichia pastoris yeast, giving the yeast the ability to turn the precursor molecule cannabigerolic ...
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).
Next, CBGA is independently converted to either CBG, THCA, CBDA or CBCA by four separate synthase, FAD-dependent dehydrogenase enzymes. There is no evidence for enzymatic conversion of CBDA or CBD to THCA or THC.
Geranyl pyrophosphate and olivetolic acid react, catalysed by an enzyme to produce cannabigerolic acid, [43] which is cyclized by the enzyme THC acid synthase to give THCA. Over time, or when heated, THCA is decarboxylated, producing THC. The pathway for THCA biosynthesis is similar to that which produces the bitter acid humulone in hops.
THC acetate ester (THC-O or THCOA) can be synthesized from THC, [1] [2] or from THCA. The acetylation of THC does not change the properties of the compound to the same extent as with other acetate esters, as the parent compound (THC) is already highly lipophilic, but potency is nonetheless increased to some extent.
