Introduction of 1492-30-4 :

4-Nitrophenyl palmitate (4-Nitrophenyl hexadecanoate) is a chromogenic substrate for lipases and esterases. Upon enzymatic hydrolysis, 4-Nitrophenyl palmitate releases p-nitrophenol, which can be quantified by colorimetric detection at 410 nm as a measure of enzymatic activity. 4-Nitrophenyl palmitate is used to characterize the activity of various bacterial and mammalian enzymes, including those from Burkholderia and porcine pancreatic lipase[1][2]. In Vitro:4-Nitrophenyl palmitate serves as a substrate for measuring esterolytic activity of porcine pancreatic lipase, Staphylococcus aureus protease, and Burkholderia sp. lipase via colorimetric detection of released p-nitrophenol, with turbidity issues resolved by adding Triton X-100 to the reaction mixture[1].
