摘要

由于其生物活性和催化活性，仅由少数氨基酸残基组成的短肽引起了人们的极大兴趣。识别它们的动态$3\mathbf{D}$结构是研究构效关系的关键。我们提出了四聚体肽催化剂的温度依赖太赫兹光谱。这些太赫兹光谱，由DFT计算支持，使我们能够区分不同肽的结构特征。

Identifying Peptide Structures with THz Spectroscopy

Short peptides composed of only a few amino acid residues are of great interest due to their biological activity and have also been shown to exhibit catalytic activity. Identifying their dynamic $3\mathbf{D}$ structure is quintessential for studying structure - activity relations. We present temperature-dependent THz spectroscopy of tetrameric peptide catalysts. These THz spectra, supported by DFT calculations, allow us to distinguish structural features of different peptides.
