Carbonyl cyanide m-chlorophenyl hydrazone (CCCP), is a chemical inhibitor of oxidative phosphorylation. It is a nitrile, hydrazone and protonophore. In general, CCCP causes the gradual destruction of living cells and death of the organism.[1][2] The CCCP affects the protein synthesis reactions in seedling mitochondria.[3] CCCP causes an uncoupling of the proton gradient that is established during the normal activity of electron carriers in the electron transport chain. The chemical acts essentially as an ionophore and reduces the ability of ATP synthase to function optimally.
