Explanation / Answer

14. Option A is correct.
A glycosidic bond is an ether linkage (-O-).

15. Option A is correct.
Carbohydrates (Monosaccharides) are readily soluble in water.

16. Option E is correct.
The greater the oxygen content in a molecule, the lesser is the reducing energy present.

17. Option A is correct.
The hydrophobic core is a tertiary structure.

18. Option D is correct.
