An oligosaccharide is made up of at least:
- A. two saccharide units
- B. ten saccharide units
- C. three to ten saccharide units
- D. more than ten saccharide units
Explanation
This is the option marked correct in the official UHS answer key, taking oligosaccharide in its broad sense of a few sugar units, beginning at two. Many textbooks instead reserve disaccharide for two units and define oligosaccharides as three to ten, which is why option (c) is such a strong distractor. Anything beyond about ten units is a polysaccharide.
