Millipede, protective secretion

Another micle<)philic addition reaction—this time in reirerae is involved in the chemical defense mechanism by which the millipede Aphe-loria corrugata protects itself from predators. When attacked by ants, it secretes the cyanohydrin maridcl-oniti ile and an enzyme that catalyze the decomposition of mandelonitriie into benzaldehyde and HCN.The millipede actually protects itself by discharging poiBonoua HCN at its attackers.
