一般說明
α-淀粉酶是唾液的主要分泌蛋白成分。它由496个氨基酸组成，具有两种亚型，即糖基化和非糖基化形式。α-淀粉酶基因位于人染色体1p21.1上。α-淀粉酶主要来自于胰腺和唾液。
我们致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。该产品针对淀粉乙醇研究进行了优化，可提高能效并防止浪费。有关详细信息，请参阅 《Biofiles》的文章。
應用
来自人唾液的α-淀粉酶已可用于通过HPLC（高效液相色谱法）测定α-淀粉酶抑制剂。它还被用于研究人乳低聚糖（HMO）的消化率。
生化／生理作用
α-淀粉酶能够催化寡糖中α-1,4糖苷键的水解。它对于淀粉、糖原和多糖的初始消化至关重要。血清淀粉酶水平升高与急性胰腺炎有关。
單位定義
在pH 6.9、温度20 °C条件下，一个单位可在3分钟内从淀粉中释放出1.0 mg麦芽糖。
外觀
冻干粉末，含有(NH4)2SO4 和柠檬酸钠
