The Fehling's Test measures how much copper can be reduced by a solution to determine how much reducing sugars are present. In a non-reducing sugar, the anomeric carbon is in an acetal. Some disaccharides and all polysaccharides are non-reducing sugars. Also, here one of the rings has five members rather than six, showing that the cyclization of fructose from the open-chain form to the hemiacetal cyclic form uses the OH at carbon 5 and the carbonyl carbon 2. Fructose is thus an example of a ketose, a sugar in which the carbonyl group is a ketone rather than an aldehyde. Presence Of Aldehyde or Ketonic Group.

Maltose contains a hemiacetal functional group and is a reducing sugar. All water soluble sugars were extracted in 30 min at 110C. Plants often store starch as a form of glucose storage. It must be quite stable if it is to serve that purpose, so enzymes specific for the alpha linkage do not attack its beta acetal functional groups and it is not readily hydrolyzed.
