Abstract This work addresses the effect of chaotropic anions (thiocyanate and tosylate) on solubility glycine, L-leucine, L-phenylalanine, L-aspartic acid in aqueous solutions at 298.2 K. The salts used were NaSCN, KSCN, NH 4 SCN, NaC 7 H SO 3 (sodium tosylate), with salt concentrations ranging from 0 to 2 molal. pH saturated was registered, solid-phase studies also performed. All thiocyanate s...

The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (L) through a bulk liquid membrane is studied experimentally and theoretically. The proposed model is based on the assumption of a pure diffusion of the complex salt [K·L]+SCN¯ through the liquid membrane stagnant films at the interfaces. It illustrates the ...

Mesoporous silica materials have been widely used as gas adsorbents due to their excellent adsorption ability, large specific surface area, simple preparation process, and convenient functionalization. In this study, a core–shell mesoporous material MCM-41@SiO2 was synthesized functionalized by CoCl2, subsequently KSCN, prepare an ammonia adsorbent. The adsorbent proved possess high good spheri...

The title one-dimensional coordination polymer, {[Zn(NCS)(2)(C(24)H(20)N(6))(2)]·0.28H(2)O}(n), was obtained by the reaction of Zn(OAc)(2)·2H(2)O, KSCN and 1,2-bis-{[2-(2-pyrid-yl)-1H-imid-azol-1-yl]meth-yl}benzene (hereafter L). The Zn(II) ion shows a distorted octa-hedral coordination geometry and is coordin-ated by two N atoms from two SCN(-) anions and four N atoms from two organic ligands....

Activation of the alternative pathway of complement commences with the formation of an initial fluid-phase C3 convertase. Treatment of C3 with the nucleophilic reagent methylamine has previously been shown to result in the cleavage of an intramolecular thioester bond and to induce C3b-like properties, including the ability to form a fluid-phase C3 convertase. This report examines the hypothesis...

Transglutaminase in the rat lung is tightly associated with the insoluble matrix which is not extractable with detergent, 0.5 M NaCl, and 40% glycerol solutions. The insoluble matrix was found to be rich in heparin sulfate and poor in collagen, elastin, and DNA. The lung transglutaminase was found to be distinct from tissue transglutaminase (identifiable with the well-characterized guinea pig l...
