General description
A substrate for serum amylase.
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.
Application
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.
Biochem/physiol Actions
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.
