Often phosphorylation or sulfation is an important step which occurs in the signal transduction and cascade of metabolic pathways. Some natural products and metabolites contain one or more sulfate or phosphate groups. Isoflavone sulfate has been identified from high-resolution mass spectrometry (HRMS) and enzymatic digestion by sulfatase. We previously… CONTINUE READING
