The following carbohydrate is
There is hydrogen at first carbon (Anomeric C) for aldohexose while alkyl group for ketohexose.
a ketohexose
an Ξ±-furanose
an Ξ±-pyranose
As the carbohydrate has six carbons, it is a hexose. Also, it has hydrogen at anomeric carbon (first carbon).
Carbohydrates are polysaccharides.
Hence, options C and D are incorrect.
Now, between options A and B, a hexose is a 6-membered ring structure, also known as furanose.
Therefore, the correct option is (B).
Note: For the keto group there should be the presence of a double bond between carbon and oxygen that was not present.
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules β Carbohydrates, Proteins, Nucleic acids and Lipids.
