General description

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。

Application

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

Follow our procedure for the determination of alpha-Amylase activity. This enzymatic assay of a-Amylase guides you through the entire process and necessary calculations.

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

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.
