Which receptor does capsaicin initially bind to, triggering the burning sensation in the mouth?
Answer
Transient receptor potential vanilloid 1 (TRPV1) receptor
The immediate sensation of heat experienced when consuming cayenne pepper is caused by capsaicin binding to the Transient Receptor Potential Vanilloid 1 (TRPV1) receptor. These receptors are specialized nerve endings that normally respond to actual physical heat or chemical irritants that signify potential tissue damage. When capsaicin binds to TRPV1, it tricks the nerve endings into firing pain signals, which the brain interprets as a burning sensation. This same receptor interaction is fundamental to capsaicin's use in topical pain treatments.
