Abstract

Condensation processes such as wet–dry cycling are thought to have played significant roles in the emergence of proto-peptides. Here, we describe a simple and low-cost method, differential Fourier transform infrared (FTIR) spectroscopy, for qualitative analysis of peptide condensation products in model primordial reactions. We optimize differential FTIR for depsipeptides and apply this method to investigate their polymerization in the presence of extraterrestrial dust simulants.

利用差分傅立叶变换红外光谱定性监测原肽缩合

干湿循环等缩合过程被认为在原肽的出现过程中发挥了重要作用。在这里，我们介绍了一种简单、低成本的方法--差分傅立叶变换红外光谱法，用于定性分析模型原始反应中的肽缩合产物。我们对差分傅立叶变换红外光谱法进行了优化，并将这种方法应用于研究在地外尘埃模拟物存在下的多肽聚合反应。
