title: Amino acid changes in abiogenic mixtures containing p-nitroaniline and p-phenylene diamine.
abstract: Mixtures containing diammonium hydrogen phosphate, ammonium molybdate, and minerals in presence of p-nitroaniline resulted in formation of glycine, methionine, phenylalanine, tryptophan, and tyrosine. Proline and valine were observed in a few tubes. When p-phenylene diamine was present in the mixture, glycine was absent, while isoleucine and leucine were observed in the tubes. Predominance of proline was observed in all the studies executed.
