BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The six membered cyclic structure of glucose is called pyranose structure or form, in analogy with Pyran.

Detailed explanation-2: -Complete answer : We have studied that Glucose is a six carbon long carbohydrate. It is a monosaccharide sugar that can be shown by linear structure or cyclic structure. Pyranose is a general term for any cyclic isomer that has five carbon atoms and one oxygen atom thereby forming a six-membered ring structure.

Detailed explanation-3: -Five and six-membered rings are favored over other ring sizes because of their low angle and eclipsing strain. Cyclic structures of this kind are termed furanose (five-membered) or pyranose (six-membered), reflecting the ring size relationship to the common heterocyclic compounds furan and pyran shown on the right.

Detailed explanation-4: -Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.
