Caffeic acid 4-O-sulfate
Caffeic acid 4-sulfate, also known as caffeate 4-sulphate or caffeic acid 4-sulphuric acid, is a member of the class of compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. Caffeic acid 4-sulfate is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Caffeic acid 4-sulfate can be found primarily in blood and urine. Within the cell, caffeic acid 4-sulfate is primarily located in the cytoplasm. It can also be found in the extracellular space. Caffeic acid 4-O-sulfate (CAS: 1213651-94-5) is a polyphenol metabolite detected in biological fluids (PMID: 20428313). Caffeic acid 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).
Caffeic acid 3-O-sulfate
Caffeic acid 3-O-sulfate (CAS: 1208232-16-9) is a polyphenol metabolite detected in biological fluids (PMID: 20428313). Caffeic acid 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).
Caffeic acid 3-sulfate
An aryl sulfate that is trans-caffeic acid in which the phenolic hydrogen at position 3 is replaced by a sulfo group. A metabolite from coffee.
