Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects monomer concentration were investigated, the resulting thin-film composite membranes tested for their performance in dye removal different flow configurations. results showed that a dense layer successfully formed on support, while with very loose structure became smoother more ...

in the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (bsa) have been analyzed on basis of intrinsic thermodynamic quantities. in this regards, the intrinsic gibbs free energy of binding, agb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...

density (r/g cm-3) and viscosity (h/10-2gcm-1s-1=1centipoise,cp) of guanosine monophosphate (gmp) and adenosine triphosphate (atp) referred to as nucleotide, and 2-deoxy adenosine (doa) and thymidine (tmd) as nucleoside along with their integral furanose sugar, 2-deoxy ribose (dor) from 0.0004 to 0.0014mol kg-1 solution have been measured at 288.15, 293.15 and 298.15k at atmospheric pressure. t...

In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...

The mechanism(s) by which fatty acids are sequestered and transported in muscle have not been fully elucidated. A potential key player in this process is the protein myoglobin (Mb). Indeed, there is a catalogue of empirical evidence supporting direct interaction of globins with fatty acid metabolites; however, the binding pocket and regulation of the interaction remains to be established. In th...

The nodC genes from rhizobia encode an N-acetylglucosaminyl transferase (chitin synthase) involved in the formation of lipo-chito-oligosaccharide Nod factors that initiate root nodule morphogenesis in legume plants. NodC proteins have two hydrophobic domains, one of about 21 residues at the N-terminus and a longer one, which could consist of two or three transmembrane spans, near the C-terminus...

The objective of this work was to select the most suitable procedure to immobilize lipase from Penicillium camembertii (Lipase G). Different techniques and supports were evaluated, including physical adsorption on hydrophobic supports octyl-agarose, poly(hydroxybutyrate) and Amberlite resin XAD-4; ionic adsorption on the anionic exchange resin MANAE-agarose and covalent attachment on glyoxyl-ag...
