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. (-5[1])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. Ed Currie recently bred an organism denoted (10[1])“X” (10[1])whose concentration of this compound exceeds that of the Carolina Reaper. (10[1])For 10 points, name this compound whose concentration in peppers is measured by the Scoville scale. ■END■
