The Oligosaccharides class of carbohydrates contain monosaccharides of about:
Correct answer: C. 2 to 10 units
- A. 2 to 8 units
- B. 2 to 9 units
- C. 2 to 10 units
- D. 2 to 11 units
Explanation
Oligosaccharides are carbohydrates composed of 2 to 10 monosaccharide units. They are formed by the joining of monosaccharide units via glycosidic bonds. Oligosaccharides that contain 2 monosaccharide units are known as disaccharides. Option C is correct because it falls within the defined range for oligosaccharides. Options A, B, and D are incorrect as they either have a narrower or broader range of monosaccharide units than what is characteristic of oligosaccharides.
