Sugar acid
A Sugar acid or acidic sugar is a monosaccharide with a carboxyl group at one end or both ends of its chain.
Main classes of sugar acids include:
- Aldonic acids, in which the aldehyde group located at the initial end of an aldose is oxidized.
- Ulosonic acids, in which the −CH2 group at the initial end of a 2-ketose is oxidized creating an α-ketoacid.
- Uronic acids, in which the −CH2 group at the terminal end of an aldose or ketose is oxidized.
- Aldaric acids, in which both ends of an aldose are oxidized.
Examples of sugar acids include:
