General description
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。
Application
α-淀粉酶用于水解α-连接多糖的α键，如淀粉和糖原。 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 米曲霉 的淀粉酶常被用作烘焙添加剂，以防止烘焙工业中的老化、净化果汁和酒精饮料的混浊物以及生产葡萄糖和麦芽糖糖浆产品 。
Biochem/physiol Actions
α-淀粉酶可水解由三个或多个α-(1,4)连接D-葡萄糖单元组成的多糖的α-(1,4)葡聚糖键。 淀粉和糖原等天然底物被分解成葡萄糖和麦芽糖。 国际免疫学会联合会（IUIS）将来自 米曲霉 （Asp o II）的α-淀粉酶归类为可引起呼吸道症状的职业过敏原 。

The commercially available alpha-amylase from Aspergillus oryzae which is widely used as a baking additive was compared with a highly purified enzyme preparation. We used enzyme allergosorbent test (EAST), EAST inhibition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), isoelectric focussing, immunoblotting
