A radiochemical assay for carboxylesterase based on the substrate methyl[1-14C]butyrate is described. The blank value corresponds to 1.04 micrograms (liver)-1.44 mg (plasma) of tissues with the highest and lowest activity respectively, which constitute the sensitivity of the method. The hydrolysis

An easily dispersible multiwalled carbon nanotube (MWCNT) derivative is prepared, and provides a platform for the synthesis of the phenyl butyric acid methyl ester (PCBM) analog. The carbene addition reaction of MWCNTs makes derivatives that are less soluble in organic

Single-unit electrophysiology was used to record the nerve impulses from the carbon dioxide receptors of female Queensland fruit flies, Bactroera tryoni. The receptors responded to stimulation in a phasic-tonic manner and also had a period of inhibition of the nerve

Purified Pseudomonas fluorescens lipase [EC 3.1.1.3] exhibited slight activity on water-soluble esters such as methyl butyrate, and this activity was increased on addition of Brij 58 (20 oxyethylene hexadecyl ether) to the solution. This stimulating effect of Brij 58 on

Carboxylesterase was purified from rat kidney in an electrophoretically homogeneous form by acetone precipitation, followed by successive chromatographies on DEAE-cellulose and hydroxyapatite and then isoelectric focusing. The purified enzyme catalyzed the hydrolyses of monoacylglycerols and short-chain triacylglycerols, such as tributyrin
