Question

Quizplus · Accepted Answer

In a ketose sugar, the carbonyl group is located in the middle of carbon chain, while in an aldose sugar, the carbonyl group is located at the end of the carbon chain. Therefore, the only option with a carbonyl group in the carbon chain is a ketose sugar, which is option E.

In Simple Sugars,every Carbon but One Contains a Hydroxyl Group;
