Sugar acid

Sugar acids are monosaccharides with a carboxyl group.

Main classes of sugar acids include:

  • Aldonic acids, in which the aldehyde functional group of an aldose is oxidized
  • Ulosonic acids, in which the first hydroxyl group of a 2-ketose is oxidised creating an α-ketoacid.
  • Uronic acids, in which the terminal hydroxyl group of an aldose or ketose is oxidized
  • Aldaric acids, in which both ends of an aldose are oxidized
  • Examples

    Examples of sugar acids include:

  • Aldonic acids
  • Glyceric acid (3C)
  • Xylonic acid (5C)
  • Gluconic acid (6C)
  • Ascorbic acid (6C, unsaturated lactone)
  • Ulosonic acids
  • Neuraminic acid (5-amino-3,5-dideoxy-D-glycero-D-galacto-non-2-ulosonic acid)
  • Ketodeoxyoctulosonic acid (KDO or 3-deoxy-D-manno-oct-2-ulosonic acid)
  • Uronic acids
  • Glucuronic acid (6C)
  • Galacturonic acid (6C)
  • Iduronic acid (6C)
  • Aldaric acids
  • Tartaric acid (4C)
  • meso-Galactaric acid (Mucic acid) (6C)
  • D-Glucaric acid (Saccharic acid) (6C)
