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.
In the Cannabis plant, THC occurs mainly as tetrahydrocannabinolic acid (THCA, 2-COOH-THC). Geranyl pyrophosphate and olivetolic acid react, catalysed by an enzyme to produce cannabigerolic acid, [42] which is cyclized by the enzyme THC acid synthase to give THCA. Over time, or when heated, THCA is decarboxylated, producing THC.
Hash oil is an extracted cannabis product that may use any part of the plant, with minimal or no residual solvent. It is generally thought to be indistinct from traditional hashish , at-least according to the 1961 UN Single Convention on Narcotic Drugs that defines these products as "the separated resin, whether crude or purified, obtained from ...
THCA, on the other hand, does not hold the same effects — unless lit. When burned, THCA turns into Delta 9 THC and likely exceeds the legal limits, Dixon said. But before it’s lit, its Delta 9 ...
However, cannabis does not naturally contain significant amounts of THC. Instead, tetrahydrocannabinolic acid (THCA) is found naturally in raw and live cannabis and is non-intoxicating. Over time, THCA slowly converts to THC through a process of decarboxylation over the course of roughly a year, but can be sped up with exposure to high ...
Cannabis plants can exhibit wide variation in the quantity and type of cannabinoids they produce. The mixture of cannabinoids produced by a plant is known as the plant's cannabinoid profile. Selective breeding has been used to control the genetics of plants and modify the cannabinoid profile.
THCA synthase is expressed in the glandular trichomes of Cannabis sativa. THCA synthase may contribute to the self-defense of Cannabis plants by producing THCA and hydrogen peroxide, which are both cytotoxic. Because these products are toxic to the plant, THCA synthase is secreted into the trichome storage cavity. [7]
Even though hemp-derived products were federally legalized six years ago, products like delta-8 can still show up as marijuana on standard drug tests.
