alleryDisaccharides whose reducing groups are bonded together are described as:
ANon-reducing sugars
BNon-recurring sugars
CNon-returning sugars

2. Bonding those groups together removes that freedom.
3. If the reducing groups of the monosaccharides are bonded, these are non-reducing sugars.
4. Sucrose is the example given.
