α-淀粉酶 来源于人类唾液Sigma
产品描述
General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch ethanol research. For more information see the article in biofiles.
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。[1]
Application
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 [2]。 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 [4]。
包装
1000, 5000 units in glass bottle
Biochem/physiol Actions
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。[3]
Unit Definition
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。
Physical form
含有(NH4)2SO4、柠檬酸钠和氯化钠的冻干粉。
