4-Nitrophenyl β-D-lactopyranoside may be used as a substrate for determining β-lactosidase activity and for determining the substrate specificity for β-glucosidase from the yeast Debaryomyces hansenii. It has also been used as a substrate for cellobiohydrolase.
p-Nitrophenyl β-D-Lactopyranoside is a useful compound
ChEBI: 4-nitrophenyl beta-lactoside is a disaccharide derivative that is beta-lactose in which the anomeric hydroxy hydrogen is replaced by a 4-nitrophenyl group. It has a role as a chromogenic compound. It is a glycoside, a C-nitro compound and a disaccharide derivative. It is functionally related to a beta-lactose and a 4-nitrophenol.
