1. Maltose is extracted from malt and it is called malt sugar. Malt from sprouting barely is the major source of maltose. Maltose is produced during digestion of starch by the enzyme α – analyse.
3. Maltose consists of two molecules of α – D glucose units linked by an α – 1, 4 – glycocidic bond between anomeric carbon ofone unit and C – 4 of the other unit. Since one of the glucose has the carbonyl group intact it act as a reducing sugar
