How many monosaccharide units do oligosaccharides yield upon hydrolysis?
Correct answer: A. 2 to 10
- A. 2 to 10
- B. 6
- C. 20
- D. 1
Explanation
Oligosaccharides are carbohydrates that yield between two and ten monosaccharide units upon hydrolysis. They occupy a middle position between monosaccharides, which cannot be hydrolyzed further, and polysaccharides, which produce more than ten monosaccharide units. For example, disaccharides like sucrose and maltose belong to this category because they yield two monosaccharides, while more complex oligosaccharides such as raffinose yield three or more. This specific range of two to ten units is what distinguishes oligosaccharides from other classes of carbohydrates and defines their structural and functional properties in biological systems.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
