Let's break down the molecular structures for both THC and CBD:
THC (Tetrahydrocannabinol)
- Molecular formula: C₂₁H₃₀O₂
- Atoms:
- Carbon (C): 21
- Hydrogen (H): 30
- Oxygen (O): 2
- IUPAC name: (−)-trans-Δ⁹-tetrahydrocannabinol
Key Features:
- THC has a cyclic ring that opens and closes, allowing for the "trans" and "cis" configurations, which are two geometric isomers. The psychoactive effect of THC is attributed to the "trans" configuration.
- It's the primary psychoactive compound in cannabis, responsible for the "high" sensation.
CBD (Cannabidiol)
- Molecular formula: C₂₁H₃₀O₂
- Atoms:
- Carbon (C): 21
- Hydrogen (H): 30
- Oxygen (O): 2
- IUPAC name: 2-[(1R,6R)-3-methyl-6-prop-1-en-2-ylcyclohex-2-en-1-yl]-5-pentylbenzene-1,3-diol
Key Features
- CBD does not possess the same cyclic structure as THC, which prevents it from inducing a psychoactive effect.
- It's been researched for various potential therapeutic benefits including anti-inflammatory, analgesic, and anti-anxiety properties.
Though THC and CBD have the same molecular formula, the difference in their arrangement of atoms (their structural isomerism) leads to their differing pharmacological effects.
