Question:

What is the name of the given structure?

Options:

β-D-(+)-glucofuranose

α-D-(+)-glucofuranose

α-D-(+)-glucopyranose

β-D-(+)-glucopyranose

Correct Answer:

β-D-(+)-glucopyranose

Explanation:

The correct answer is option 4. β-D-(+)-glucopyranose

The α and β forms of glucose can be represented as a six-membered ring called pyranose, resembling the organic compound pyran. Since the OH group of anomeric n carbon is at the same side to the OH at C3 carbon, it is the β-form of glucopyranose.
