生化/生理作用：
4-Nitrophenyl N-acetyl-β-D-glucosaminide (NP-GlcNAc) is a widely used hexosaminidase substrate. Enzymatic action cleaves the glycosidic bond and forms 4-nitrophenolate (pNP) which is measured at 405 nm. NP-GlcNAc can also be used in combination with diethylaminoethyl-a-cyclodextrin (DEn-CD) for a rapid and accurate rate assay method for b-N-acetylglucosaminidase. The cyclodextrin derivative is used as an additive to ionize 4-nitrophenol to yellow-colored 4-nitrophenoxide at a pH near 5, the pH optimum for the enzyme.
