Glucogallin is chemical compound formed from gallic acid and β-D-glucose. It can be found in oaks species like the North American white oak (Quercus alba), European red oak (Quercus robur) ^[1] and Amla fruit (Phyllanthus emblica).^[2]

It is formed by a gallate 1-beta-glucosyltransferase (UDP-glucose: gallate glucosyltransferase), an enzyme performing the esterification of two substrates, UDP-glucose and gallate to yield two products, UDP and glucogallin. This enzyme can be found in oak leaf preparations.^[3]

This the first step in the biosynthesis of gallotannins. The molecule is then used by enzymes in the gallotannins synthetics pathway like beta-glucogallin O-galloyltransferase or beta-glucogallin-tetrakisgalloylglucose O-galloyltransferase.

Half-life of β-Glucogallin in human body seems to be unknown.
