Maltose is another disaccharide obtained by partial hydrolysis of starch or made of two units of D-glucose.
In maltose, C-1 of one α-Dglucose is linked to C-4 of another α-Dglucose molecule by glycosidic linkage.
The glucose ring which uses its hydroxyl group at C-1 is α – 1 → 4 glycosidic linkage.
It is a reducing sugar because a free aldehyde group can be produced at C1 of second glucose molecule.
Maltose on hydrolysis with dilute acids gives glucose.
