Taming A Poison: Saving Plants From Cyanide With Carbon Dioxide

The scientific world is one step closer to understanding how nature uses carbon-capture to tame poisons, thanks to a recent discovery of cyanoformate by researchers at Saint Mary's University (Halifax, Canada) and the University of Jyväskylä (Finland). This simple ion — which is formed when cyanide bonds to carbon dioxide — is a by-product of the fruit-ripening process that has evaded detection for decades. Chemists have long understood the roles presence of cyanide (CN−) and carbon dioxide (CO2) in fruit ripening, but have always observed them independently. This is the first time scientists have isolated the elusive cyanoformate anion (NCCO2−) and characterized its structure using crystallography and computational chemistry. read more
