Collection: pNP(para-Nitrophenyl) Glycosides [Glyco Building Blocks]

pNP(para-Nitrophenyl) Glycosides [Glyco Building Blocks] — gathers glycosides linked to para-nitrophenyl (pNP) groups, such as 4-Nitrophenyl beta-D-Cellobioside and 4-Nitrophenyl alpha-D-Glucuronide Sodium Salt, including complex oligosaccharides such as Disialylnonasaccharide-beta-pNP. The pNP group in this class functions as a chromogenic marker that is released when the glycosidic bond is hydrolyzed by specific enzymes.

pNP Glycosides are widely used by glycobiology and enzymology researchers as synthetic substrates for measuring glycosidase activity through the release of the yellow color of the nitrophenolate group during enzymatic hydrolysis. Compounds such as 4-Nitrophenyl 2-Acetamido-2-deoxy-beta-D-glucopyranoside and its galactopyranoside derivatives are commonly used in spectrophotometric assays, while complex structures such as Neu5Ac alpha(2-6)GalNAc-alpha-pNP support studies of carbohydrate recognition by lectins or specific enzymes.

Selection should consider the anomeric configuration (alpha or beta), the type of constituent monosaccharides, and the complexity of the oligosaccharide structure to match the specificity of the enzyme or receptor under study. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
