| Hazard Information | Back Directory | [Description]
P-nitrophenyl butyrate also kown as 4-nitrophenyl butyrate, is a probe for lipase activity. It is hydrolyzed by lipase in the water ambient condition, giving rise to p-nitrophenol and butyric acid. P-nitrophenol actually occurs in the anionic form, p-nitrophenolate, giving a yellowish coloration and absorbing light at 410 nm in an alkaline buffer such as Tris-HCl pH 7.5. | [Uses]
4-Nitrophenyl butyrate is a substrate for esterase, and lipase enzyme. Hydrolysis of 4-nitrophenyl butyrate by these enzymes releases the chromophore, 4-nitrophenolate which is spectrophotometrically analysed at 415 nm. | [Uses]
A probe for lipase activity. | [Definition]
ChEBI: A butyrate ester resulting from the formal condensation of the hydroxy group of 4-nitrophenol with the carboxy group of butyric acid. | [General Description]
4-Nitrophenyl butyrate is a substrate for esterase, and lipase enzyme. Hydrolysis of 4-nitrophenyl butyrate by these enzymes releases the chromophore, 4-nitrophenolate which is spectrophotometrically analysed at 415 nm. | [References]
