| BioCyc:ALPHA-AMYL-RXN | 1-4-alpha-D-Glucan + ∞ WATER --> ∞ 1-4-alpha-D-Glucan | In general the reaction is the endohydrolysis of 1,4-α-D-glucosidic linkages in polysaccharides containing three or more 1,4-α-linked D-glucose units. |
| BioCyc:RXN0-5181 | 1-4-alpha-D-Glucan + ∞ WATER --> 1-4-alpha-D-Glucan + MALTOHEXAOSE | |
| BioCyc:3.2.1.1-RXN | Starch + WATER --> MALTOSE + Glucose | Endohydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides containing three or more (1→4)-α-linked D-glucose units.Acts on starch, glycogen and related polysaccharides and oligosaccharides in a random manner; reducing groups are liberated in the α-configuration. The term "α" relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolysed. |
