| Popis: |
Amino acids, nucleic acid bases and organic acids were synthesized by the UV irradiation of aqueous solutions in which CO 2 and NH 3 gases or ammonium carbonate had been dissolved. For the photosyntheses of amino acids and nucleic acid bases, the irradiation of UV light of wavelengths shorter than 280 nm at temperatures higher than 80 °C and the coexistence of Mg 2+ in the solution were found to be effective. Oxalic acid and/or oxamic acid were assumed to be possible intermediates for the syntheses. |
