The product has been evaluated for the conversion of ethyl butyrate to butyric acid and ethanol. However, there has been no evaluation for the hydrolysis of ethyl hexanoate into hexanoic acid, and there are no known citations of this product for ethyl hexanoate hydrolysis. Due to the structural similarity between ethyl hexanoate and ethyl butyrate, both containing an ester bond, it's possible that this product could hydrolyze ethyl hexanoate, as esterases typically accommodate a wide range of ester substrates. However, the rate and efficiency of the hydrolysis may differ from the enzyme activity tested using ethyl butyrate as a substrate.

General description
Application
Esterase from rabbit liver has been used in a study to investigate a toxic effect of carbamate insecticides. Esterase from rabbit liver has also been used in a study to investigate the effect of simvastatin on expression and activity of a lipoprotein-associated phospholipase A(2).
Esterase from rabbit liver has been used:
- in comparative biophysical studies with bovine bile-salt-activated lipase in the assays with vinyl acetate, triacylglycerols, p-nitrophenyl esters and serine enzyme inhibitors[1]
- in the catalysis and kinetic profiling studies of peptidic compounds[3]
- in in vitro stability assays of prodrug compounds (BMS-292655 and BMS300043)[4]
- in the hydrolysis of oleuropein aglycone (Ole-AG)[5]
The enzyme from Sigma has been used to study the effect of divalent metal ions on the activity of esterase.[6]
Biochem/physiol Actions
Esterase enzyme catalyzes hydrolysis of carboxylic ester to carboxylate and alcohol in the presence of water. Rabbit liver carboxylesterase catalyzes enantioselective hydrolysis of cineol derivatives.[7]
Physical form
Lyophilized powder containing Tris buffer salts
Other Notes
One unit will hydrolyze 1.0 μmole of ethyl butyrate to butyric acid and ethanol per min at pH 8.0 at 25 °C.

To explore the potential of step-by-step assembly in the fabrication of biological materials, we designed and synthesized two peptide-based molecules for enzyme-instructed hierarchical assembly. Upon the treatment of alkaline phosphatase, one molecule undergoes enzyme-instructed self-assembly forming uniformed nanofibers. The other

To differentiate esterases from lipases at the structure-function level, we have compared the kinetic properties and structural features of sequence-related esterase 1 from rabbit liver (rLE) and bile-salt-activated lipase from bovine pancreas (bBAL). In contrast to rLE, bBAL hydrolyses water-insoluble

Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) contributes to atherosclerotic plaque instability and subsequent sudden coronary death. Statins are associated with decreased stroke risk and may improve stability of atherosclerotic plaques. The present study investigated the effect of simvastatin on expression of Lp-PLA(2)

Animal data strongly support a role for inflammation in myocardial ischemia reperfusion injury. Attempts at cardioprotection by immunomodulation (such as with the specific C5 antibody pexelizumab) in humans have been disappointing. We hypothesized that a broader spectrum antiinflammatory agent might
