Which statement describes the relationship between Anandamide and CB1 receptors?

• A. It is a lipid-based endogenous ligand.
• B. It is a serotonin transporter inhibitor.
• C. It is a non-lipid protein.
• D. It does not interact with CB1.

Answer: (A)

Anandamide is part of the body's endocannabinoid system and acts as a natural signal that binds to cannabinoid receptors, especially CB1, in the brain. It is a lipid-based endogenous ligand, meaning it is derived from fatty acids and is hydrophobic, not a protein or a small molecule that inhibits transporters. When it binds CB1, it modulates neurotransmitter release and influences functions like pain, mood, and appetite. It is rapidly degraded by the enzyme FAAH after signaling. This makes the statement that it is a lipid-based endogenous ligand for CB1 the best description, rather than being a serotonin transporter inhibitor, a non-lipid protein, or something that doesn’t interact with CB1.
