As a large number of the annotated features were matched with conjugated analytes, the new MassQL algorithm was used to aid in confirming if the features had a glucuronide (176.0321 Da) or sulfate (79.9573 Da). From the 245 polyphenolic features, 74 features had a sulfate conjugation, and 35 had a glucuronide conjugation. While for other xenobiotic features, six had a glucuronide conjugation and 12 had a sulfate conjugation. These results overcome a previous study by Jarmusch et al. in which seven metabolites were identified with MassQL to have a sulfate.
