Metabolite Identification
Common NameIsoferulic acid
DescriptionIsoferulic acid (CAS: 537-73-5) is a chlorogenic acid (CGA). CGAs are formed by the esterification of hydroxycinnamic acids (e.g. caffeic acid, ferulic acid, and p-coumaric acid) with quinic acid. CGAs are abundant phenolic compounds in coffee, with caffeoylquinic (CQA), feruloylquinic (FQA), and dicaffeoylquinic (diCQA) acids being the major subclasses, and coffee is the most consumed food product in the world. Isoferulic acid is present in normal human urine in concentrations of 0.05-2.07 umol/mmol creatinine at baseline, and reaches 0.2-9.6 umol/mmol creatinine in four hours after a cup of coffee, with a large inter-individual variation (PMID: 17884997 ).
