The molecule is a carboxylic ester resulting from the formal condensation of the carboxylic acid group of mycophenolic acid with the anomeric hydroxy group of beta-D-glucuronic acid. It is a beta-D-glucosiduronic acid, a gamma-lactone, a member of phenols and a carboxylic ester. It derives from a mycophenolic acid and a beta-D-glucuronic acid. It is a conjugate acid of a mycophenolic acid O-acyl-glucuronide(1-).
