4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside for detecting α-galactosidase activity. The amount of released pNP is significantly increased when PNP-alpha-D-Gal is used as substrates.

Description | 4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside for detecting α-galactosidase activity. The amount of released pNP is significantly increased when PNP-alpha-D-Gal is used as substrates. |
In vitro | Using 4-nitrophenol (pNP)-glycopyranosides as pseudosubstrates, the amount of liberated pNP from the 4-Nitrophenyl α-D-galactopyranoside is significantly higher than that from the other pNP-glycopyranosides at pH 4.0 while no activity was detected at pH 7.0. The digestion assays using pNP glycopyranosides as artificial substrates exhibit that yielding liberated galactose residues from 4-Nitrophenyl α-D-galactopyranoside mainly at pH 4.0, i.e. the pH level where yield threshold is decreased at most. |
