一般描述
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。
生化/生理作用
α-淀粉酶由包含496个氨基酸的单个多肽链组成。它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。天然底物（如淀粉和糖原）可被分解成葡萄糖和麦芽糖。
外形
从含有NaCl和CaCl2的Tris缓冲液中冻干。
制备说明
利用Levitzki等人开发的改良方法进行制备。
其他说明
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。

Carbohydrate digestibility is a key determinant for elevated postprandial hyperglycemia (PPHG). Apart from dietary restrictions, one of the strategies to reduce PPHG is to limit the activity of carbohydrate digestive enzymes within the gastrointestinal tract in order to reduce monosaccharide
