ketose
Sugar with carbonyl
A ketose is a simple sugar whose molecular structure contains a ketone group, as opposed to an aldose, which contains an aldehyde group.
Fructose is the most familiar ketose—the sugar that makes fruit sweet.
The distinction matters in biochemistry, where the two types of sugars behave differently in metabolic reactions.
