To have an effect, a molecule must bind to a receptor and trigger a signal.  Studying a receptor’s structure can give us insights about the way this triggering process works. Capsaicin is a fascinating molecule that puts the “pep” into peppers.  Curiously, the amount of capsaicin in a pepper is measured with a test devised in 1912 by…
