    在美拉德模型系统中,N末端氨基酸对由肽形成吡嗪的影响。
    摘要:
    文献中美拉德反应研究的一小部分集中在碳水化合物和肽之间的反应上。因此,在先前的研究中,其中该肽的影响的延续Ç端氨基酸进行了研究,该研究集中在肽的影响Ñ端氨基酸上生产的葡萄糖,甲基乙二醛的模型反应吡嗪类,或乙二醛。选择了九个不同的二肽和三个三肽。结果表明,N-末端氨基酸的结构决定了吡嗪的总产量。特别是在N上脯氨酸,缬氨酸或亮氨酸的情况下,2,5(6)-二甲基吡嗪和三甲基吡嗪的产量较低-末端,而对于甘氨酸,丙氨酸或丝氨酸则很高。与烷基取代的吡嗪相反,在用游离氨基酸进行实验的情况下,未取代的吡嗪总是产生更多。显然,对此观察结果必须负责不同的机制。这项研究清楚地说明了肽产生风味化合物(例如吡嗪)的能力。

    peptide C-terminal amino acid was investigated, this study focused on the influence of the peptide N-terminal amino acid on the production of pyrazines in model reactions of glucose, methylglyoxal, or glyoxal. Nine different dipeptides and three tripeptides were selected. It was shown that the structure of the N-terminal amino acid is determinative for the overall pyrazine production. Especially, the production
