研究了胶原（大鼠和鳕鱼皮）及其相关化合物（聚脯氨酸、聚甘氨酸和多三肽）的红外酰胺I波段。对固态和水溶液中聚脯氨酸II和多肽（Gly‐Pro‐Pro）和（Gly‐Pro‐Gly）n的酰胺I波段组分进行了分配。在多肽光谱中观察到的三种酰胺I成分在每个三联体中被归因于三个不同的肽CO基团。在此基础上，对胶原蛋白和同构寡肽和多肽中的酰胺I多组分结构进行了解释。讨论了胶原蛋白和相关化合物中涉及肽CO基团的分子内和分子间氢键的顺序。
The infrared amide I band of collagens (rat and cod skin) and related compounds (polyproline, polyglycine, and polytripeptides) was studied. Assignment of amide I‐band components for polyproline II and polytripeptides (Gly‐Pro‐Pro)nand (Gly‐Pro‐Gly)nin the solid state and water solution was made. Three amide I components observed in the polypeptide spectra were attributed to three different peptide CO groups in each triplet. On the basis of this assignment, the interpretation of the amide I multicomponent structure in collagen and isomorphous oligo‐ and polypeptides was attempted. The ordering of intra‐ and intermolecular hydrogen bonds involving peptide CO groups in collagen and related compounds was discussed.
