Escherichia coli K-12 substr. MG1655 Compound: oxalate

Synonyms: oxalic acid, ethanedioic acid

Summary from MetaCyc:
Oxalate is the most oxidized two-carbon compound. It is made in high concentrations by some plants and fungi and can reach high micromolar concentrations in soil. Oxalate is toxic to mammals but is metabolized by many bacteria and plants by various pathways. In high concentrations, it causes death in humans and animals because of its corrosive effects, while smaller amounts can cause various pathological disorders, including hyperoxaluria, calcium oxalate stones, pyridoxine deficiency, and even renal failure.

Chemical Formula: C2O4
