4-硝基苯-α-D-吡喃半乳糖苷 用途与合成方法

生物活性

4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) 是一种 4-硝基苯基 (pNP) 糖吡喃糖苷的人工底物，用于检测 α-半乳糖苷酶活性。当 4-Nitrophenyl α-D-galactopyranoside 用作底物时，释放的 pNP 量会显着增加。

体外研究

Using 4-nitorophenol (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 whereas no activity was detected at pH 7.0.  
 The digestion assays using 4-nitrophenyl (pNP) glycopyranosides as artificial substrates shows that yieldin 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.

用途 

α-D-半乳糖苷酶（α-D-Galactosidase）的底物。结合到大肠杆菌乳糖蛋白载体上。α-D-牛乳糖用培养基
