4-Nitrophenyl a-D-mannopyranoside

4-Nitrophenyl a-D-mannopyranoside is a chromogenic pNP enzyme substrate that enables the detection and quantification of a-D-mannosidase activity in various biological samples through a colorimetric assay. The hydrolysis of the substrate by the enzyme releases 4-nitrophenol, a yellow compound whose absorption can be measured spectrophotometrically. Applications for this substrate span biomedical research, disease diagnostics, and industrial enzyme production.
