A series of twenty four analogues of L-α–Asp–Gly–Gly–OMe has been synthesized in relation to structural features of sweet peptides. The rule in the structure-taste relationships of dipeptides is held in the sweet aspartyl tripeptide esters. In order for the aspartyl tripeptide esters to be sweet, the second amino acid must have a D-configuration and a small, compact alkyl group (Me, Et, or i-Pr) at
已经合成了与甜肽的结构特征相关的一系列 24 种 L-α-Asp-Gly-Gly-OMe 类似物。二肽的结构-味道关系的规则在于甜天冬氨酰三肽酯。为了使天冬氨酰三肽酯具有甜味,第二个氨基酸必须具有 D 构型,并且在 R2 处有一个小的、紧凑的烷基(Me、Et 或 i-Pr)。强烈的甜味需要第三个氨基酸的 L 构型。已经得出结论,R2 处的小烷基通过疏水相互作用参与与受体的结合并增加甜味效力。
