This paper demonstrates Pseudomonas cepacia lipase catalyzed hydrolysis of p-nitrophenyl palmitate under irradiation of light with wavelengths of 250-750 nm. The reaction follows Michaelis-Menten Kinetics and the light irradiation increases the overall rate of hydrolysis. Using Lineweaver-Burk plot K M and V max values for the reaction in presence of light are found to be 39.07 and 66.67 mM/min...

Exploring cobalt phosphide catalysts with abundant active sites and outstanding intrinsic activity for robust hydrogen evolution reaction (HER) oxygen (OER) is highly desirable. Herein, by the fine-tuning thermal-reduction treatment of phosphonates spherical shape, novel carbon-wrapped CoP-Co2P polymorphs are rationally constructed. The unique hierarchical porous architecture heterointerface no...

Glutamate synthase (GltS, EC 1.4.1.13) forms with glutamine synthetase (GS, EC 6.3.1.2, reaction 1) the main route for glutamate synthesis in micro-organisms by catalysing the NAD(P)Hdependent transfer of the amide group of glutamine to the C(2) carbon of 2-oxoglutarate (2-OG, reaction 2). The overall reaction catalysed by GS and GltS (reaction 3) is similar to the reaction of glutamate dehydro...

reaction mechanism among indoline-2,3-dione, pyrrolidine-2-carboxylic acid and (z)-2-(1-(2-hydroxynaphthalen-1-yl)ethylidene)hydroxycarboxamide to form 1’-((((aminooxy)carbonyl)amino)methyl)-2’-(1-hydroxynaphthalen-2-yl)-2’-methyl-1’,2’,5’,6’,7’,7a’-hexahydrospiro[indoline-3,3’-pyrrolo[1,2-a]imidazole-2-one was investigated using density functional theory (dft) at b3lyp basis theory. the three-...

PURPOSE Host immune response to tumor may be an important prognostic factor for colon cancer patients. However, little is known on prognostic significance of histopathologic lymphoid reaction to tumor, independent of the number of lymph nodes examined and tumoral molecular alterations, including microsatellite instability (MSI) and the CpG island methylator phenotype (CIMP), both of which are a...

the stability constants and complexation reaction between l-glutamine, l-arginine andglycine with zn (ii) , co (ii) and ni (ii) were studied potentiometrically in aqueous solution at25° c and μ=0.1 m kno3. the overall stability constants log β´s of all species are obtained bycomputer refinement of ph-volume data using best computer program. several models weretested and the lowest δfit, the bes...

The highly exoergic nucleophilic substitution reaction F(-) + CH3I shows reaction dynamics strikingly different from that of substitution reactions of larger halogen anions. Over a wide range of collision energies, a large fraction of indirect scattering via a long-lived hydrogen-bonded complex is found both in crossed-beam imaging experiments and in direct chemical dynamics simulations. Our me...

background: the whoqol-bref is one of the best-known instruments that have been developed for cross-cultural compari­sons of quality of life and currently it is available in more than 40 languages. current study was done to provide: (1) the psychometrics properties of the iranian version of whoqol-bref and (2) the norm scores for satisfaction with life over­all and satisfaction with specific li...
