Urolithin C 3-glucuronide

(2S,3S,4S,5R,6S)-6-({8,9-Dihydroxy-6-oxo-6H-benzo[C]chromen-3-yl}oxy)-3,4,5-trihydroxyoxane-2-carboxylic acid

C19H16O11 (420.0693)


Urolithin C 3-glucuronide belongs to the class of organic compounds known as phenolic glycosides. These are organic compounds containing a phenolic structure attached to a glycosyl moiety. BioTransformer predicts that urolithin C 3-glucuronide is a product of urolithin C metabolism via an aromatic-OH-glucuronidation reaction catalyzed by the UDP-glucuronosyltransferase 1-1 (P22309) enzyme (PMID: 30612223).

C12H22NO9S3 (420.0457)


4-methylthiobutyl glucosinolate is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). 4-methylthiobutyl glucosinolate can be found in a number of food items such as arrowroot, ohelo berry, winged bean, and buffalo currant, which makes 4-methylthiobutyl glucosinolate a potential biomarker for the consumption of these food products.
