A neuropeptide with diverse biological activities
Phenolphthalein β-D-glucuronide is a colorimetric substrate for β-glucuronidase.1 Upon enzymatic cleavage by β-glucuronidase, phenolphthalein is released, which can be quantified by colorimetric detection at 552 nm as a measure of β-galactosidase activity.1,2
