4-Nitrophenyl α-L-Rhamnopyranoside is a chromogenic substrate for naringinase.
4-Nitrophenyl α-L-rhamnopyranoside has been used as a substrate to determine β-glucosidase activity. It has also been used as a substrate to measure α-L-rhamnosidase activity of Oenococcus oeni and Aspergillus terreus.
4-Nitrophenyl α-L-rhamnopyranoside is a substrate for determining α-L-rhamnosidase activity. The hydrolysis of 4-Nitrophenyl α-L-rhamnopyranoside by the enzyme yields 4-nitrophenol, measured at 405 nm spectrophotometrically.
