Ethylidene-4-nitrophenyl-a-D-Maltoheptaoside

Ethylidene-4-nitrophenyl-a-D-Maltoheptaoside (pNP-G7) is the substrate of α-amylase. Ethylidene-4-nitrophenyl-a-D-Maltoheptaoside is degraded by amylase in the presence of auxiliary enzymes (such as α-glucosidase) to release the chromophore, allowing the measurement of amylase activity. Ethylidene-4-nitrophenyl-a-D-Maltoheptaoside can be used for the diagnosis of pancreatitis[1][2].
