Chemical Information
FooDB Name2-Furancarboxylic acid
DescriptionIsolated from roots of Phaseolus vulgaris (kidney bean) Furoic acid is a metabolite that appears in the urine of workers occupationally exposed to furfural and is marker of exposure to this compound. Furfural is a heterocyclic aldehyde that is commonly used as a solvent in industry. It is readily absorbed into the body via the lungs and has significant skin absorption. Furfural is an irritant of the eyes, mucous membranes, and skin and is a central nervous system depressant. Furfural as a confirmed animal carcinogen with unknown relevance to humans (It has been suggested that is a substance that produces hepatic cirrhosis). Once in the body, furfural is metabolized rapidly via oxidation to the metabolite furoic acid, which is then conjugated with glycine and excreted in the urine in both free and conjugated forms. (PMID: 3751566, 4630229, 12587683). Furoic acid is a biomarker for the consumption of beer.
