Escherichia coli K-12 substr. MG1655 Compound: malonate

Synonyms: malonyl, propanedioic acid, malonic acid

Summary from MetaCyc:
Malonate is found in small amounts in plants [Bentley52] and is produced by some bacteria [Vogels76]. However, most of the malonate in the environment comes from industrial production. The dimethyl and diethyl forms, in particularly, are produced at more than 12,000 tons per year (1995) [Dimroth97].

Chemical Formula: C3H2O4
