What sense do peppers have on the tongue bitter sour salty or sweet?

Peppers are known for their spicy flavor, which is actually a chemical sensation rather than a taste. Here's how it works:

* Capsaicin: Peppers contain a compound called capsaicin, which activates a type of pain receptor in your mouth called the TRPV1 receptor.

* Heat: This activation creates a burning sensation, often described as "heat," that's distinct from the four basic tastes (sweet, sour, salty, bitter).

While peppers might have a slightly sweet or bitter taste depending on the variety, the main sensation they evoke is heat due to capsaicin.
