Receptor proteins that allow us to sense heat have been isolated as well as molecules that cause us to perceive heat such as hot pepper and wasabi. If such proteins are able to detect as little as 20.0 μg of capsaicin, the chemical responsible for the burn in peppers, how many molecules of capsaicin (C18H27NO3) are required before the tongue can detect it?
