Bongkrek acid is a respiratory toxin more deadly than cyanide. [Peter J. F. Henderson and Henry A. Lardy, "Bongkrekic acid: An Inhibitor of Adenine Nucleotide Translocase of Mitochondria", Journal of Biological Chemistry, (1970) 245, 6, 1319. [http://www.jbc.org/cgi/content/abstract/245/6/1319 Abstract, includes structure] ]

It is produced in fermented coconut contaminated by the bacterium "Burkholderia gladioli" pathovar "cocovenenans". In particular, it has been implicated in deaths resulting from eating the soybean and coconut-based product known as tempe bongkrèk , which is banned in Indonesia.

It is highly toxic because of its effect on the ATP-ADP translocase mechanism. It shuts this system down, preventing ATP from leaving the mitochondria and providing energy to the rest of the cell.
