Question

Quizplus · Accepted Answer

The main difference between aldose sugars and ketose sugars is the position of the carbonyl group. In aldose sugars, the carbonyl group is located at the end of the carbon chain and is therefore an aldehyde. In ketose sugars, the carbonyl group is located in the middle of the chain and is therefore a ketone. The number of carbons, the position of the hydroxyl groups, and the form (ring or linear chain) can vary between different types of sugars, but they are not specific to aldoses or ketoses.
