A protected sperm whale myoglobin-(77–96)-eicosapeptide (23) was synthesized by a solution method. The protected peptide 23 could be effectively purified by silica-gel column chromatography with 1-butanol–acetic acid–water as the eluate. The CD spectra of protected fragment peptides were measured in a solution of 2,2,2-trifluoroethanol. A protected sperm whale myoglobin-(85–96)-dodecapeptide and 23
通过溶液法合成了受保护的抹香鲸肌红蛋白-(77-96)-二十肽 (23)。受保护的肽 23 可以通过
硅胶柱色谱法以
1-丁醇-
乙酸-
水为洗
脱液进行有效纯化。在
2,2,2-三氟乙醇溶液中测量受保护片段肽的 CD 光谱。受保护的抹香鲸肌红蛋白-(85-96)-十二肽和 23 显示出螺旋结构特征的 CD 剖面。
