Question

Quizplus · Accepted Answer

All of the answer choices are possible sugar derivatives. There are many possible modifications that can be made to a sugar molecule by an organism, including oxidation of the carbonyl carbon, replacing a hydroxyl group with an amino group, oxidizing a carbon atom to a carboxyl group, and replacing a hydroxyl group with a hydrogen atom. Therefore, option E is the correct answer as it states that all of the answer choices are possible sugar derivatives.
