D(+)-Maltose monohydrate

D-(+)-Maltose monohydrate is a component of starch and glycogen. It is a sugar composed of 2 α-D-glucose molecules coupled by an α(1→4) glycosidic bond. It is a reducing sugar with one anomeric carbon not linked in an anomeric bond. It contains a hemiacetal function and can mutarotate. Maltose is one product generated from starch and glycogen by the action of α-amylase.


  • Mixed anomers


Maltose can be further hydrolysed to glucose by the action of α-glucosidase (maltase), an enzyme commonly found in yeast and many other sources. It is called malt sugar when it is formed in fermenting grains during the production of alcoholic beverages.


D-(+)-Maltose monohydrate is used as a sweetener with about one-third the sweetness of sucrose and as a nutrient in culture media. It is used in pharmaceutical formulations and as a parenteral supplement of sugar for diabetics.
