Concept:Oligosaccharides are carbohydrates that yield
2 to
10 monosaccharide units upon hydrolysis.
Explanation:Oligosaccharides are classified according to the number of monosaccharide units produced on hydrolysis.
Hydrolysis breaks the glycosidic bond present in the carbohydrate to release its constituent monosaccharides.
A disaccharide specifically contains two monosaccharide units linked by a glycosidic bond.
Sucrose on hydrolysis produces two monosaccharide units, namely
Glucose and
Fructose.
Therefore,
Sucrose is a disaccharide, which is a type of oligosaccharide.
Ribose,
Fructose, and
Glucose are all monosaccharides.
Monosaccharides cannot be further hydrolysed into simpler sugars.
Hence, among the given options, only
Sucrose is correctly classified as an oligosaccharide.
Answer:Option
B:
Sucrose.
