一般說明
人α-淀粉酶由包含496个氨基酸的单个多肽链组成，其在1号染色体上进行编码。其在唾液腺或胰腺中产生。唾液和胰腺α-淀粉酶具有同源的一级序列，但表现出不同的切割模式。
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。当用于淀粉乙醇研究时，该产品经优化可提高能效和防止浪费。有关详细信息，请参阅 《Biofiles》的文章。
應用
α-淀粉酶可用于水解α-连接多糖（例如淀粉和糖原）的α键。产品A1031来自人唾液，属IIA型，并以冻干粉末形式提供。α-淀粉酶已被用于各种植物研究，如 拟南芥 的代谢研究 。 来自人类唾液的α-淀粉酶已被用于营养保健品的开发，其可能有助于治疗糖尿病和肥胖症 。
生化／生理作用
α-淀粉酶可水解三个或更多个D-葡萄糖单元通过α-（1,4）连接的多糖中的α-（1,4）葡聚糖键。天然底物（如淀粉和糖原）可被分解成葡萄糖和麦芽糖。
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
含有(NH4)2SO4、柠檬酸钠和氯化钠的冻干粉。
