Common Name | Amylose |

Description | Amylose is defined as a linear molecule of (1→4) linked alpha-D-glucopyranosyl units, but it is today well established that some molecules are slightly branched by (1→6)-alpha-linkages. The oldest criteria for linearity consisted in the susceptibility of the molecule to complete hydrolysis by beta-amylase. This enzyme splits the (1→4) bonds from the non-reducing end of a chain releasing beta-maltosyl units, but cannot cleave the (1→6) bonds. When degraded by pure beta-amylase, linear macromolecules are completely converted into maltose, whereas branched chains give also one beta-limit dextrin consisting of the remaining inner core polysaccharide structure with its outer chains recessed. Starches of different botanical origins possess different granular sizes, morphology, polymorphism and enzyme digestibility. These characteristics are related to the chemical structures of the amylopectin and amylose and how they are arranged in the starch granule (PMID 9730163 ). |
