一般描述

淀粉是植物中的碳水化合物储备，也是人类能量的主要来源。在植物中，淀粉存在于叶片的叶绿体、块茎和种子的淀粉质体中。在结构上，淀粉由两种主要的多糖组成，即直链淀粉和支链淀粉。两者均由-(1,4)-连接 D-葡萄糖残基通过-(1,6)-糖苷键相互连接的链组成。马铃薯淀粉在功能上优于其他淀粉，因为它的脂类级别低。淀粉的营养成分包括快速消化淀粉、慢速消化淀粉和抗性淀粉 (RS)。淀粉酶是淀粉降解酶。淀粉消化率受食物中碳水化合物含量、淀粉营养成分和烹调食物等因素的影响。抑制胰淀粉酶对延缓淀粉消化，防止餐后高血糖有重要的治疗作用。 食品工业用淀粉作增稠剂。

应用

来自马铃薯的淀粉已被用作 α-淀粉酶抑制试验，通过使用生熟食品样品和瓜蒌 （Linn）的地上部分，作为测定 SusG 活性的底物，使用 DNSA 试验测定动物肠道菌群活性。

实验方案

Enzymatic Assay of Pectinase

To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.

果胶酶的酶促检测

在测定果胶酶活性时，使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下，一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。

淀粉葡萄糖苷酶的酶学测定（EC 3.2.1.3）

本操作程序可用于使用淀粉作为底物测定淀粉葡萄糖苷酶的活性。

Enzymatic Assay of Amyloglucosidase (EC 3.2.1.3)

This procedure may be used for the determination of Amyloglucosidase activity using starch as the substrate.
