A bitter heptapeptide BPIa was synthesized and compared with the natural peptide, isolated by Minamiura et al. from casein hydrolyzate, by means of thin layer chromatography, paper electrophoresis, and carboxymethylcellulose column chromatography. All results for the two peptides matched very closely each other. The synthetic BPIa has an extremely bitter taste with its threshold value 0.05 mM. It is one of the most bitter compounds such as phenylthiourea and quinine.
通过薄层色谱法、纸电泳法和羧甲基纤维素柱色谱法,合成了一种苦味七肽 BPIa,并将其与 Minamiura 等人从酪蛋白水解物中分离出的天然肽进行了比较。两种肽的所有结果都非常吻合。合成的 BPIa 具有极苦的味道,阈值为 0.05 mM。它是苯硫脲和奎宁等最苦的化合物之一。
