Application
Phenolphthalein β-D -glucuronide has been used as a substrate for the detection of β-D -glucuronidase activity in fecal bacteria.
β-glucuronidase activity was determined by the amount of phenolphthalein released from 0.01 M henolphthalein β-D-glucuronide.
Biochem/physiol Actions
Phenolphthalein β-D -glucuronide is a chromogenic substrate for β-glucuronidase enzyme and the resultant colored product of the reaction is measured at 552 nm.
