1H- and 13C-n.m.r. measurements enable direct observation of the rate of formation of dehydroalanine residues resulting from lysis of the disulphide bonds of insulin and oxidized glutathione in base at pD13. The data provide clear evidence for the beta-elimination mechanism for this reaction. The dehydroalanine-containing products from the lysis of insulin undergo secondary reactions.
1H核磁共振和13C核磁共振测量能够直接观察到在pD13的碱性条件下,胰岛素和氧化型谷胱甘肽的二硫键裂解所产生的脱氢丙氨酸残基的形成速率。这些数据为该反应的β-消除机制提供了明确的证据。胰岛素裂解产生的含脱氢丙氨酸的产物会发生二级反应。
