Ulosonic acid
Encyclopedia
An ulosonic acid is a sugar acid obtained by the oxidation of the 1-hydroxyl group of a ketose
to a carboxylic acid
, creating an alpha-keto acid
. An example of an ulosonic acid is ketodeoxyoctulosonic acid.
Ketose
A ketose is a sugar containing one ketone group per molecule.With 3 carbon atoms, dihydroxyacetone is the simplest of all ketoses and is the only one having no optical activity. Ketoses can isomerize into an aldose when the carbonyl group is located at the end of the molecule...
to a carboxylic acid
Carboxylic acid
Carboxylic acids are organic acids characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH, where R is some monovalent functional group...

Keto acid
Keto acids are organic compounds that contain a carboxylic acid group and a ketone group. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in glycolysis...
