Identification
Name: Dextrin
Description:Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen. Dextrins are mixtures of polymers of D-glucose units linked by -(1_4) or -(1_6) glycosidic bonds. The cyclical dextrins are known as cyclodextrins. They are formed by enzymatic degradation of starch by certain bacteria, for example, Bacillus macerans. Cyclodextrins have toroidal structures formed by 6-8 glucose residues. (Wikipedia) In Pseudomonas aeruginosa metabolism, the enzyme alpha-amylase (EC 3.2.1.1) catalyzes the breakdown of glycogen into dextrin. (KEGG)
