| Hazard Information | Back Directory | [Uses]
Amylose is a polyglucose polysaccharide which together with amylopectin makes starch(s). 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 agent, a gelling agent and emulsion stabilizer. Amylose is used in the preparation of films and membranes with potential use in drug delivery. | [Definition]
A polymer of GLUCOSE,
a polysaccharide sugar that is found
in starch. | [Definition]
amylose: A polysaccharide consistingof linear chains of between 100and 1000 linked glucose molecules.Amylose is a constituent of starch.In water, amylose reacts with iodineto give a characteristic blue colour. | [Definition]
The inner, relatively soluble portion of starch granules. Amylose is a hexosan, a polymer of glucose, and consists of long, straight chains of glucose units joined by a 1,4-glycosidic linkage. It stains blue with iodine. Microcrystalline amylose is available chiefly as a food ingredient and dietary energy source. | [Agricultural Uses]
Amylose is a type of polysaccharide and is a constituent
of starch. Amylose is made up of linear links of several
hundred glucose molecules. A water-amylose mixture
turns blue when iodine is added to it. | [Biological Activity]
Amylose is a polyglucose polysaccharide th at makes starch(s) together with amylopectin. The glucosidic bonds of amylopectin are α-1,4 linkages. Amylose is used to identifydifferentiate and characterize amylase(s). Amylose is used as a thickening and gelling agentand emulsion stabilizer. Amylose is used to prepare films and membranes with potential use in drug delivery. | [Purification Methods]
Amylopectin is removed from impure amylose by dispersing in aqueous 15% pyridine at 80-90o (concentration 0.6-0.7%) and allowing the solution to stand at 44-45o for 7days. The precipitate is re-dispersed and recrystallises during 5days. After a further dispersion in 15% pyridine, it is cooled to 45o, allowed to stand at this temperature for 12hours, then cooled to 25o and left for a further 10hours. The combined precipitates are dispersed in warm water, precipitated with EtOH, washed with absolute EtOH, and dried in vacuo [Foster & Paschall J Am Chem Soc 75 1181 1953]. |
