In order to elucidate the structure-taste relationship of bitter peptide BPIa (Arg–Gly–Pro–Pro–Phe–Ile–Val), cyclo-BPIa was synthesized. The result of both taste and CD examinations suggested that the bitterness of BPIa is caused by its spatial structure, which is analogous to that of cyclo-BPIa.
为了阐明苦味肽B
PIa(Arg-Gly-Pro-Pro-Phe-Ile-Val)的结构-味道关系,合成了环B
PIa。味觉和 CD 检测结果表明,B
PIa 的苦味是由其空间结构引起的,这种结构与环 B
PIa 类似。
