生物活性
4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) 是一種 4-硝基苯基 (pNP) 糖吡喃糖苷的人工底物，用于檢測(cè) α-半乳糖苷酶活性。當(dāng) 4-Nitrophenyl α-D-galactopyranoside 用作底物時(shí)，釋放的 pNP 量會(huì)顯著增加。體外研究
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.
