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。
