  2. Osazone - Wikipedia

    en.wikipedia.org/wiki/Osazone

    Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.

    en.wikipedia.org/wiki/Hydrazone

    Phenylhydrazine reacts with reducing sugars to form hydrazones known as osazones, which was developed by German chemist Emil Fischer as a test to differentiate monosaccharides. [ 4 ] [ 5 ] Uses

  4. Amadori rearrangement - Wikipedia

    en.wikipedia.org/wiki/Amadori_rearrangement

    The reaction is associated with the amino-carbonyl reactions (also called glycation reaction, or Maillard reaction) [3] in which the reagents are naturally occurring sugars and amino acids. One study demonstrated the possibility of Amadori rearrangement during interaction between oxidized dextran and gelatine.

  5. Seliwanoff's test - Wikipedia

    en.wikipedia.org/wiki/Seliwanoff's_test

    An example of a positive Seliwanoff’s test. Seliwanoff’s test is a chemical test which distinguishes between aldose and ketose sugars. If the sugar contains a ketone group, it is a ketose. If a sugar contains an aldehyde group, it is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than ...

    Fischer projection of D-glyceraldehyde. Like most carbohydrates, simple aldoses have the general chemical formula C n (H 2 O) n.Because formaldehyde (n=1) and glycolaldehyde (n=2) are not generally considered to be carbohydrates, [1] the simplest possible aldose is the triose glyceraldehyde, which only contains three carbon atoms.
