This compound’s ability to inhibit NADH dehydrogenase in Fusarium suggests that it initially evolved as a fungal growth inhibitor. This is the most common injected compound used to induce c-Fos and pERK expression in primary sensory neurons. This compound is the primary analgesic found in Qutenza patches. Vanillotoxin triggers the same chemical response as exposure to this compound because both bind to the calcium channel TRPV1 (“trip-V-one”). This antagonist of substance P does not bind to avian thermoreceptors, explaining why birds are not repelled by this compound. (10[2])Ed Currie recently bred an organism denoted “X” whose concentration of this compound exceeds that of the Carolina Reaper. For (10[1])10 points, name this compound whose concentration in peppers is measured by the Scoville scale. ■END■
