THE POSSIBLE INVOLVEMENT OF Cu2+PEPTIDE/PROTEIN COMPLEXES IN THE FORMATION OF ETHYL CARBAMATE

Abstract
Ethanolic solutions of bovine serum albumin or wheat gluten were shown to form ethyl carbamate subsequent to distillation or reflux in the presence of copper. Substitution of propanol for ethanol resulted in the formation of propyl carbamate. The reflux of an ethanolic solution of essential amino acids, in the presence of copper, did not result in significant formation of ethyl carbamate.
