MetaCyc Compound Class: D-glucuronate

Synonyms: glucuronate, glucuronic acid, D-glucuronic acid, GlcA, D-glucopyranuronic acid

Superclasses: all carbohydrates a carbohydrate a glycan a sugar a monosaccharide a hexose a D-hexose
an acid all carboxy acids a carboxylate

Summary:
D-glucuronate is a carboxylic acid that often forms a hexapyranose ring structure. It is common in carbohydrate chains of proteoglycans and is part of mucous animal secretions (such as saliva), cell glycocalyx and intercellular matrix

The hexapyranosic form β-D-glucuronate is found in the glycosaminoglycans chondroitin sulfate, dermatan sulfate, heparin, heparan sulfate and hyaluronan.

Child Classes: D-glucopyranuronate (2)

Instances:
aldehydo-D-glucuronate
