Prebiotic synthesis was simulated by the elec. discharge of a mixture of HCN-H2O. The formation of amino acids (e.g., glycine, serine, isoleucine, and aspartic acid) urea, cyanate, formamide, and formaldehyde was suggested based on 14C labeling and paper chromatog. Qual. chem. evidence suggested peptide or peptidelike substance in the products of the elec. discharge experiment
