3.2.2.4. Oxidation products
3.2.2.4 Oxidation products
When aldosed are oxidised under proper conditions with different types of oxidising products, three types of acids are produced.
1. Aldonic acid
2. Uronic acid
3. Saccharic acid
1. Aldonic acid: Oxidation of an aldose with bormine water at neutral pH converts the aldehyde group to a carboxyl group.
D Glucose → Gluconic acid
2. Uronic acid: When aldoses are oxidised with H2O2 uronic acids are formed. Uronic acids are constituents of pectic polysaccharides.
3. Saccharic acid or Aldaric acid: When aldoses are oxidised with nitric acid saccharic acids are formed. Glucose forms glucosaccharic acid and galactose produces mucic acid.
