Which of the following carbons are present outside the ring of fructose?
Correct answer: D. 1st carbon and 6th carbon
- A. 1st carbon & 2nd carbon
- B. 1st carbon and 5th carbon
- C. Only Ist carbon
- D. 1st carbon and 6th carbon
Explanation
Fructose can form a five cornered ring structure called fructofuranose, having four carbons and an oxygen atom within the ring while the first and last carbons remain outside the ring, i.e., 1st carbon and 6th carbon.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
