Identify the non-reducing sugar from the following.
Identify the non-reducing sugar from the following.
Maltose
Sucrose
Lactose
Glucose
Solution
Sucrose is made up of two monosaccharide glucose and fructose.
These two monosaccharides are held together by glycosidic linkage between $C_1$ of glucose and $C_2$ of fructose. Since, reducing groups of glucose and
glycosidic bond formation and are not available for reducing reaction. Hence, sucrose is a non-reducing sugar. Hence, option (2) is correct.
