Description

2-Naphthyl caprylate is a chromogenic substrate for carboxylesterase and lipase. 2-naphthol is released upon hydrolyzation. By simultaneous coupling with a diazonium salt, the corresponding azo-dye is formed.

Naphthols can also be detected by fluorescence analysis, and can be used in a colorimetric assay for the extracellular lipase of Pseudomonas fluorescent B52.

Description

Nitrophenyl-β-D- glucopyranoside acts as a chromogenic substrate for β-Glucosidase. When cleaved, Nitrophenyl-β-D- glucopyranoside produces a yellow solution, and its appearance can be measured spectrophotometically.

The study of β-Glucosidase is particularly important as this enzyme is necessary for cell wall degradation and is inherent in some fungi and bacterial pathogens.
