The furan ring is an important structural component of biological molecules. How many carbon atoms are required to form ribofuranose?
Correct answer: B. 5
- A. 3
- B. 5
- C. 6
- D. 2
Explanation
Ribofuranose is a type of sugar molecule that contains a furan ring structure. The furan ring is a five-membered ring that contains four carbon atoms and one oxygen atom. Therefore, five carbon atoms are required to form ribofuranose.
