Metabolite Identification
Common Namedelta-9-tetrahydrocannabinolate
Descriptiondelta9-tetrahydrocannabinolate is also known as thca or δ9-tetrahydrocannabinolic acid. delta9-tetrahydrocannabinolate is practically insoluble (in water) and a moderately acidic compound (based on its pKa). delta9-tetrahydrocannabinolate can be found in a number of food items such as devilfish, arrowhead, potato, and cereals and cereal products, which makes delta9-tetrahydrocannabinolate a potential biomarker for the consumption of these food products.
