Maltose
Lactose
Fructose
Solution
In disaccharides, if the reducing groups of monosaccharides i.e., aldehydic or ketonic groups are bonded, these are non-reducing sugar e.g., sucrose. On the other hand, sugars, in which these functional groups are free, are called reducing sugars for example, maltose and lactose.
