Quizplus · Accepted Answer

Aldoses are a type of monosaccharide (simple sugar) that contain an aldehyde group. In their linear form, aldoses have one carbon atom that is part of the aldehyde group and is not included in the ring structure when the sugar cyclizes. This means there is only 1 carbon atom outside the ring in an aldose.
