Question

Quizplus · Accepted Answer

The main difference between an aldose sugar and a ketose sugar is the position of the carbonyl group. In an aldose sugar, the carbonyl group is located at the end of the carbon chain and is always an aldehyde. In a ketose sugar, the carbonyl group is located in the middle of the carbon chain and is always a ketone. The number of carbons and the position of the hydroxyl groups are not specific to either aldose or ketose sugars. Additionally, both aldose and ketose sugars can exist in both linear and ring forms.
