Question

The pyranose structure of glucose is ____________.

Options

• a homocyclic five-membered structure

• a homocyclic six-membered structure

• a heterocyclic five-membered structure

• a heterocyclic six-membered structure

Answer 1

The pyranose structure of glucose is a heterocyclic six-membered structure.

Explanation:

Because they resemble pyran, a six-membered heterocyclic ring having five carbon atoms and one oxygen atom, glucose's six-membered cyclic ring structures are called pyranose structures.
