Is Sucrose an Aldehyde or Ketone?

Sucrose, or common table sugar, is a disaccharide made from two simpler monosaccharides: glucose and fructose. While glucose contains an aldehyde group and fructose contains a ketone group, sucrose itself is neither an aldehyde nor a ketone because these reactive functional groups are locked in a glycosidic bond. This structural arrangement is what makes sucrose a non-reducing sugar.
