Biochem/physiol Actions
4-Nitrophenyl N-acetyl-α-D-galactosaminide serves as a chromogenic synthetic substrate for lysosomal enzyme α-N-acetylgalactosaminidase to perform enzyme assays. Upon cleavage the substrate forms a yellow color solution of p-nitrophenol that can be measured at 400nm at pH 10.6.

This paper presents a new assay to determine the activity of the lysosomal enzyme α-N-acetylgalactosaminidase (Naga, EC 3.2.1.49) in human serum. It is based on the use of a new chromogenic substrate, DNP-α-GalNAc (2,4-dinitrophenyl-N-acetyl-α-D-galactosaminide) and is performed at pH 4.3 and
