In order to study the role of hydrophobicity in bitter peptides, several O-aminoacyl sugars, in which amino acids or peptides were attached to the 2- and 3-position of methyl α-D-glucopyranoside, were synthesized and sensory analyses were carried out. It was found that the bitterness increased as the hydrophobicity of compounds increased, implying that the bitterness receptor recognizes the hydrophobicity of bitter peptides. A structure for the bitterness receptor is also discussed.
为了研究疏
水性在苦味肽中的作用,合成了几种 O-
氨基酰基糖,其中
氨基酸或肽附着在甲基 α-D
吡喃
葡萄糖苷的 2 位和 3 位上,并进行了感官分析。结果发现,随着化合物疏
水性的增加,苦味也随之增加,这意味着苦味受体能识别苦味肽的疏
水性。此外,还讨论了苦味受体的结构。
