Chemistry of Delta-9-THC
A. Chemical Structure and Molecular Formula of Delta-9-THC
Delta-9-THC, also known as (-)-trans-delta-9-tetrahydrocannabinol, is a cyclic terpenoid compound with a molecular formula of C21H30O2. It consists of a pentyl side chain attached to a dibenzopyran ring system.
B. Isomerism and Stereochemistry of Delta-9-THC
Delta-9-THC exhibits stereoisomerism, with two chiral centers in its structure. The stereochemistry of Delta-9-THC is important as it can affect its pharmacological properties and interactions with biological receptors. The two enantiomers of Delta-9-THC are (-)-trans-delta-9-THC and (+)-trans-delta-9-THC, with the former being the more common and more potent form.
C. Physicochemical Properties of Delta-9-THC
Delta-9-THC is a lipophilic compound, meaning it is soluble in fats and oils but insoluble in water. It has a melting point of around 65-70°C and a boiling point of approximately 157°C. These properties contribute to its ability to bind to fatty tissues and accumulate in the body after consumption.
Metabolism of Delta-9-THC
A. Step-by-Step Breakdown of Delta-9-THC in the Body
After ingestion or inhalation, Delta-9-THC is rapidly absorbed into the bloodstream and distributed throughout the body. It undergoes extensive metabolism in the liver, primarily through enzymatic reactions. The major metabolic pathway involves the oxidation of Delta-9-THC to 11-hydroxy-delta-9-tetrahydrocannabinol (11-OH-THC) by the enzyme cytochrome P450 2C9 (CYP2C9). Subsequently, 11-OH-THC is further metabolized to 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH).
B. Enzymes Involved in the Metabolism Process
Several enzymes are involved in the metabolism of Delta-9-THC, including CYP2C9, CYP3A4, and UDP-glucuronosyltransferases (UGTs). These enzymes play a crucial role in the conversion of Delta-9-THC into its metabolites, which are then excreted from the body.
