Application

4-Nitrophenyl valerate has been used as a substrate solution to measure the rate of p-nitrophenol formation using p-nitrophenyl valerate as substrate. It has also been used as a substrate to measure general esterase activity in hepatopancreas extracts.

Biochem/physiol Actions

4-Nitrophenyl valerate acts as a model substrate for carboxylesterase and butyrylcholinesterase.

An enzyme capable of hydrolysing pectenotoxins (PTXs) and okadaic acid (OA) esters within the hepatopancreas of the Greenshell™ mussel Perna canaliculus was isolated and characterized. The enzyme was purified by sequential polyethylene glycol fractionation, anion exchange, hydrophobic interaction, gel filtration

Herein, the synthesis of enzyme-polymer conjugates is reported. Four different activated polymers (mPEG-aldehyde, mPEG-NHS, maltodextrin-aldehyde, carboxymethyl cellulose aldehyde) are conjugated to the surface of protease, α-amylase, and lipase using two different strategies (reductive amination and alkylation with NHS-activated acid).

Hepatic carboxylesterases (Ces) catalyze the metabolism of drugs, environmental toxicants, and endogenous lipids and are known to be regulated by multiple nuclear receptors. Perfluorooctanoic acid (PFOA) is a synthetic fluorochemical that has been associated with dyslipidemia in exposed populations. In
