對(duì)硝基苯基-b-D-葡萄糖苷, 4-Nitrophenyl b-D-glucopyranoside

4-Nitrophenyl-β-D- glucopyranoside is a chromogenic β-D-glucosidase substrate, producing a yellow solution upon cleavage.

4-Nitrophenyl β-D-glucopyranoside is a chromogenic substrate for β-glucosidase. Upon hydrolysis by β-glucosidase, 4-nitrophenol is released, which can be quantified by colorimetric detection at 405 nm as a measure of β-glucosidase activity.

4-nitrophenyl beta-D-glucoside is a beta-D-glucoside that is beta-D-glucopyranose in which the anomeric hydroxy hydrogen is replaced by a 4-nitrophenyl group. It has a role as a chromogenic compound. It is a beta-D-glucoside and a C-nitro compound. It derives from a 4-nitrophenol.
