DescriptionEnt-gallocatechin, also known as (2s,3r)-flavan-3,3',4',5,5',7-hexol or (2s,3r)-gallocatechin, is a member of the class of compounds known as epigallocatechins. Epigallocatechins are compounds containing epigallocatechin or a derivative. Epigallocatechin is a flavan-3-ol containing a benzopyran-3,5,7-triol linked to a 3,4,5-hydroxyphenyl moiety. Ent-gallocatechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Ent-gallocatechin can be found in common grape and tea, which makes ent-gallocatechin a potential biomarker for the consumption of these food products.
