Question: 49
4. The formation of α-d-glucopyranose from β-d-glucopyranose is called:
- A. glycosidation.
- B. mutarotation.
- C. enantiomerization.
- D. racemization.
Correct Answer: B
Explanation:
Mutarotation is the interconversion between anomers of a compound. Enantiomerization and racemization, choices (C) and (D), mean the same thing as each other: the formation of a mirror-image or optically inverted form of a compound. Glycosidation, choice (A), is the addition of a sugar to another compound.
