Metabolite Identification
Common Name(-)-Epigallocatechin 3-(4-methyl-gallate)
Description(-)-epigallocatechin 3-(4-methyl-gallate), also known as 3-O-(4-O-methylgalloyl)epigallocatechin or 4"-methyl-(-)-epigallocatechin 3-gallate, is a member of the class of compounds known as catechin gallates. Catechin gallates are organic compounds containing a gallate moiety glycosidically linked to a catechin (-)-epigallocatechin 3-(4-methyl-gallate) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa) (-)-epigallocatechin 3-(4-methyl-gallate) can be found in tea, which makes (-)-epigallocatechin 3-(4-methyl-gallate) a potential biomarker for the consumption of this food product (-)-epigallocatechin 3-(4-methyl-gallate) can be found primarily in blood and urine. (-)-Epigallocatechin 3-(4-methyl-gallate) is a constituent of oolong tea (Camellia sinensis)..
