Description

一般描述

Amylose, a ubiquitous carbohydrate polymer in starch, is made up of a long α-1,4-linked linear chain with rare α-1,6-linked branch points. It is usually seen in the amorphous regions of the granule. It has a left-handed α-helical structure with one turn of the helix consisting of six to eight anhydroglucose units.

应用

直链淀粉是一种多聚葡萄糖多糖，与支链淀粉一起构成淀粉。 支链淀粉的葡萄糖键是α-1,4键。直链淀粉用于鉴定、鉴别和表征淀粉酶。直链淀粉用作增稠剂、胶凝剂和乳液稳定剂。直链淀粉用于制备具有药物释放潜力的薄膜和膜。

Amylose from potatoes has been used as a standard to determine the apparent amylose content (AAC) of rice starch by the iodine-binding colorimetric method.

生化/生理作用

Amylose is a polyglucose polysaccharide that makes starch(s) together with amylopectin. The glucosidic bonds of amylopectin are α-1,4 linkages. Amylose is used to identify, differentiate and characterize amylase(s). Amylose is used as a thickening and gelling agent, and emulsion stabilizer. Amylose is used to prepare films and membranes with potential use in drug delivery.
