The influence of protecting groups on the β-sheet-structure stability of protected peptides was studied in organic solvents. α-Amino groups, carboxyl groups, and side-chain functional groups of model peptides were protected by availably used protecting groups. The difference between the solubilities of model peptides was investigated by the solvent-titration method using infrared (IR) absorption spectra
在有机溶剂中研究了保护基团对受保护肽的 β-折叠结构稳定性的影响。模型肽的α-氨基、羧基和侧链官能团被可用的保护基团保护。通过使用红外 (IR) 吸收光谱的溶剂滴定法研究模型肽的溶解度之间的差异。除了 Npys、Mts 和 Z2 之外,每个保护基团的 β-折叠结构稳定电位 (SPβ) 表现出相似的行为。结果表明,被保护肽的值几乎与其保护基的种类无关。
