| Name | Maltose |
|---|
| Description | Sweetening agent, dietary supplement. Occurs in some plants as hydrolytic dec. production of starch. Production in high yield (80%) by the action of diastase (a- and b-amylase) on starch, a process used in brewing
Maltose is a disaccharide formed from two units of glucose joined with an alpha(1->4)bond. Maltose is the disaccharide produced when amylase breaks down starch. It is found in germinating seeds such as barley as they break down their starch stores to use for food. It is also produced when glucose is caramelized. |
