Metabolite Identification
Common NameOxalic acid
DescriptionOxalic acid, also known as oxalate or ethanedioic acid, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Oxalic acid exists as a solid, possibly soluble (in water), and a moderately acidic compound (based on its pKa) molecule. Oxalic acid exists in all living organisms, ranging from bacteria to humans. Oxalic acid is a potentially toxic compound. Oxalic acid has been found to be associated with several diseases known as hemodialysis and uremia; also oxalic acid has been linked to several inborn metabolic disorders including glycolic aciduria, primary hyperoxaluria I, and fumarase deficiency.
