organophosphorus compounds are known to inhibit the esteratic site of acetylcholinesterase by phosphorylation. the phosphorylated esteratic site of acetylcholinesterase undergoes hydrolytic regeneration at a slow or negligible rate. nucleophilic agents such as hydroxytamine, hydroxamic acids, and oximes reactivate the enzyme more erapidfy than does spontaneous hydrolysis. the red cell cholinest...

The response of several Escherichia coli membranous enzymes to hydrolysis of up to 95 % of membrane phospholipid has been investigated. Purified phospholipase C of Bacillus cereus was utilized in these studies. The rate and extent of digestion of E. coli phospholipids was independent of whether the lipid was associated with membrane protein or extracted from membranes and sonically dispersed. P...

pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...

MnCo2O4 (MnO-Co2O3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (SEM-EDX) and X-ray diffraction (XRD) techniques. In this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...

A series of complexes of the type trans-[Co(acacen)(amine)2]ClO4, where (acacen) is the (bis(acetyleacetone) ethylenediimine) and the amines are Benzyl amine (bzlan) 1, 2-amino pyrimidine (2ampy) 2, N-methylpipirazine (nmpip) 3, 3-methyl pyridine (3mpy) 4, p-toluidine (p-toldn) 5, has been synthesized and characterized by uv-vis. and FT-IR. The kinetics of the substitu...

An improved model for enzymatic hydrolysis of cellulose is developed that considers oligomer reactions with beta-glucanases, inhibition of oligomers to cellulases and enzyme decay processes during hydrolysis. Our oligomer reactions with beta-glucanases are modeled based on the enzymatic glucan chain fragmentation kinetics to describe the further fragmentation of oligomers in solution after bein...

Neisseria gonorrhoeae readily underwent autolysis when suspended in N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid (HEPES) buffer at alkaline pH values. Autolysis was inhibited by the addition of Mg2+ or other divalent cations. Autolysis was also suppressed at acid pH (pH 6.0). Suspension of cells in buffer was accompanied by the hydrolysis of peptidoglycan. The rate of peptidoglycan hydro...
