What is the chemical name for the compound responsible for the cooling sensation in mint leaves?
Show answer & explanation
Correct answer: D
Explanation
The Correct Answer is option 4 i.e. Menthol.
The compound responsible for the cooling sensation in mint leaves is Menthol. It is a naturally occurring organic compound found in peppermint and other mint plants. Menthol interacts with cold-sensitive receptors in the skin and mucous membranes, specifically the TRPM8 receptor, which tricks the brain into sensing cold even when there’s no actual temperature change. This is why menthol is widely used in products like toothpaste, chewing gum, balms, and cold medications for its soothing, cooling effect. Its refreshing aroma also adds to its popularity in food, cosmetics, and medicinal products.
