Chemical Information
FooDB NameCaffeic acid 4-O-sulphate
DescriptionCaffeic 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.
