The correct answers are:
Sorbitol: G
It is alcoholic derivative of Glucose, in which the aldehyde group is reduced to an alcoholic group.
D-2-deoxyglucose: A
The Oxygen on the second carbon of D-glucose is removed, to give 2-deoxyglucose.
D-glucosamine: H
The amino group in D-glucoseamine has the same orientation as that of the H on 3rd carbon. (The option D shows L-glucosamine, not D-glucosamine).
D-glucuronic acid: E
Uronic acids contain both carbonyl group (-CHO or -C=O) and carboxylic acid functional groups. The hydroxyl group of the terminal alcohol is oxidized to carboxylic aicd.
