研究在太空普遍的条件下进行肽合成，并对其产物进行全面分析表征。¹³C的应用使研究人员能够确认，由于C+CO+NH₃反应中形成的氨基烯分子聚合而产生的肽形成途径。研究解决了如何通过水分子的存在改变肽生产效率的问题。结果证明，虽然水稍微降低了氨基烯的聚合效率，但它并不阻止多肽的形成。

据介绍，由于在星际介质分子相的低温条件下原子碳的凝聚，蛋白质前体的形成为生命的起源开辟了另一条途径。

Abstract: The formation of protein precursors, due to the condensation of atomic carbon under the low-temperature conditions of the molecular phases of the interstellar medium, opens alternative pathways for the origin of life. We perform peptide synthesis under conditions prevailing in space and provide a comprehensive analytic characterization of its products. The application of ¹³C allowed us to confirm the suggested pathway of peptide formation that proceeds due to the polymerization of aminoketene molecules that are formed in the C + CO + NH₃ reaction. Here, we address the question of how the efficiency of peptide production is modified by the presence of water molecules. We demonstrate that although water slightly reduces the efficiency of polymerization of aminoketene, it does not prevent the formation of peptides.
