Sinapic acid 4-O-sulfate
C11H12O8S (304.02528720000004)
Sinapic acid 4-O-sulfate is an endogenous phenolic acid metabolite. Sinapic acid 4-O-sulfate was found to be elevated in rat urine after whole rye consumption which makes this compound a potential urinary biomarker of whole grain intake (PMID: 26862900).
Arctinone A acetate
Arctinone a acetate is a member of the class of compounds known as bi- and oligothiophenes. Bi- and oligothiophenes are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Arctinone a acetate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Arctinone a acetate can be found in burdock, which makes arctinone a acetate a potential biomarker for the consumption of this food product.
