The Uses of 4-Nitrophenyl acetate
4-Nitrophenyl Acetate have been used as a substrate to study for the enzymatic activity of Carbonic Anhydrase III isolated from bovine skeletal muscle.
The Uses of 4-Nitrophenyl acetate
4-Nitrophenyl acetate is used with iodoacetic acid for reductive cleavage of methionine-containing peptides. It is also used as a substrate that has been used in assays for esterase and lipase activity. Inorganic complexes have been evaluated for their methanolysis or hydrolysis activity using p-nitrophenyl acetate.
What are the applications of Application
4-Nitrophenyl acetate is a chromogenic esterase substrate
Definition
ChEBI: An acetate ester resulting from the formal condensation of the hydroxy group of 4-nitrophenol with the carboxy group of acetic acid.
