11-Hydroxyhexahydrocannabinol

11-Hydroxyhexahydrocannabinol (11-OH-9α-HHC and 11-OH-9β-HHC, or alternatively 7-OH-HHC under the monoterpenoid numbering system) is an active metabolite of tetrahydrocannabinol (THC) and a metabolite of the trace cannabinoid hexahydrocannabinol (HHC). In a pathway that parallels the metabolism of the THC family of cannabinoids, following ingestion HHC undergoes hepatic metabolism by cytochrome p450 (predominantly the CYP3A4 isozyme, with some contribution from CYP2C9 and CYP2C19) to a multitude of oxygenated derivatives, including 8-OH-HHC and 11-OH-HHC. C11-oxidation is the major pathway of THC and HHC metabolism.
