Asparagine is an important amino acid for abiotic polypeptide synthesis. In simulation experiments, it was obtained in 3.0% yield (based on the amount of consumed alanine) from alanine (100 mM) and formamide (200 mM) by contact glow discharge (Harada discharge) onto aqueous solutions. The present results suggest that asparagine could be abiotically synthesized from simple amino acids under possible primitive earth conditions.

Asparagine, one of the most important amino acids for prebiotic peptide formation in aqueous media, was formed using Contact Glow Discharge Electrolysis (CGDE) against aqueous solutions containing simple amino acids and carboxylic acid amides.
Drawing inspiration from the initiating amino acid modification in biosynthetic peptides, we have successfully demonstrated a biomimetic mechanism for N-to-C terminal extension in prebiotic peptide synthesis. This achievement was accomplished by using acetylated amino acid amides as the N-terminal substrate for peptide synthesis and amino acid amides as the C-terminal extension, with the reaction carried
受生物合成肽中起始氨基酸修饰的启发,我们成功证明了益生元肽合成中 N 至 C 末端延伸的仿生机制。这一成果是通过使用乙酰化氨基酸酰胺作为肽合成的N端底物,以氨基酸酰胺作为C端延伸,反应在80℃下以干湿循环进行,不需要任何活化剂。这为益生元肽的形成提供了一条合理的途径。
