Application
4-nitrophenyl palmitate has been used as a substrate for lipase enzyme activity.
General description
4-Nitrophenyl palmitate is a substrate for lipase enzyme activity. Lipase hydrolyzes 4-nitrophenyl palmitate and yields the yellow colored product 4-nitrophenol, which is measurable spectrophotometrically at 410 nm. This method is advantageous due to its short reaction time and facile spectrophotometric analyses. The cell-bound lipase has preference for 4-nitrophenyl palmitate as substrate than the extracellular lipase.

Herein, as a promising support, a magnetic enzyme nanoformulation have been designed and fabricated by a poly-o-toluidine modification approach. Owing to the magnetic nature and the existence of amine functionalized groups, the as-synthesised poly(o-toluidine) functionalized magnetic nanocomposite (Fe3O4@POT) was employed
