HYDROGEN CYANIDE DIMER AND CHEMICAL EVOLUTION

Hydrogen Cyanide Dimer and Chemical Evolution.

The hypothesis that life originated by a process of slow chemical evolution has been the basis of many attempts to synthesize biochemical molecules under simulated primitive earth conditions. Since the primitive atmosphere is believed to have been strongly reducing, consisting essentially of the hydrides of hydrogen, carbon, nitrogen, and oxygen,'-3 experiments have been directed toward the syn...

Metabolism of hydrogen cyanide by higher plants.

A survey has been made of the occurrence and distribution of three enzymes which metabolize cyanide in a variety of higher plants including both cyanogenic and non-cyanogenic species. The enzymes investigated were beta-cyanoalanine synthase, rhodanese and formamide hydrolyase. beta-Cyanoalanine synthase was found to be present in every higher plant tested whereas rhodanese was found to occur fa...
