General description

分子质量：51-54 kDa。
从猪胰腺中分离的α-淀粉酶是一种糖蛋白。它是由约475个残基组成的一条多肽链（包含2个SH基团和4个二硫键）以及一个紧密结合的Ca2+ （稳定性所必需的）组成的。氯离子是活性和稳定性所必需的。活性pH范围为5.5至8.0，最适pH为7。
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。

Application

α-淀粉酶用于水解α-连接多糖的α键，如淀粉和糖原。 Sigma的α-淀粉酶已被用于各种植物研究，如 拟南芥 的代谢研究 。 猪胰腺α-淀粉酶在研究番茄的淀粉代谢和成熟过程中被用于去除淀粉 。

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。 猪胰腺α-淀粉酶是一种糖蛋白，由约475个残基组成的一条多肽链（包含2个SH基团和4个二硫键）以及一个紧密结合的Ca2+ （稳定性所必需的）组成。 最适pH为7。
