taste of BPIa, the analogs containing D-proline or glycine in place of the L-proline in the 3- or 4-positions were synthesized. The bitter taste of [D-Pro3,4]–BPIa (lD-D), [D-Pro3]–des–Pro3–BPIa (2D), and [Gly3]–des–Pro3–BPIa lacking the L-proline residue was much weaker than that of the peptides containing the L-proline, BPIa (1L-L), 1L-D, 1D-L, and 2L. The CD curves of these analogs and BPIa were measured
为了阐明BPIa的化学结构和苦味之间的关系,合成了含有D-脯氨酸或甘氨酸代替3-或4-位的L-脯氨酸的类似物。[D-Pro3,4]–BPIa (1D-D)、[D-Pro3]–des–Pro3–BPIa (2D) 和 [Gly3]–des–Pro3–BPIa 的苦味缺乏 L-脯氨酸残基比含有 L-脯氨酸、BPIa (1L-L)、1L-D、1D-L 和 2L 的肽弱得多。这些类似物和 BPIa 的 CD 曲线是在水中测量的。结果表明,BPIa 的苦味是由归因于 L-脯氨酸残基的空间结构引起的。
