maltose and maltotriose were chemically synthesised as substrates for human pancreatic α-amylases and subjected to kinetic analysis. Rates measured were shown to reflect both hydrolysis and transglycosylation reactions. 4-O-Methylated derivatives of these substrates underwent only hydrolysis, thereby simplifying kinetic analyses. These modified substrates may be used for the detection and kinetic analysis
化学合成麦芽糖和麦芽三糖的衍生物作为人胰腺α-淀粉酶的底物,并进行动力学分析。已显示测得的速率反映了水解反应和转糖基化反应。这些底物的4-O-甲基化衍生物仅进行水解,从而简化了动力学分析。这些修饰的底物可用于α-淀粉酶的检测和动力学分析,可用于快速筛选新型α-淀粉酶抑制剂和随后的动力学表征。
