The crystal structure of the title Schiff base complex is obtained by single-crystal X-ray diffraction data.The solid state structure determination reveals that the coordination geometry around the copper(II) center istetrahedrally distorted square-planar. The crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

Aiming at studying cooperativity effects between amino acids in easily accessible protein models, we have explored the chemistry of peptide dendrimers, which obtain as pure products by solid-phase synthesis using a branching diamino acid such lysine every second or third position sequence, followed reverse-phase HPLC purification. This article reviews discoveries driven combinatorial library an...

a semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant ph value and constant temperature in the various relative supersaturations. results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the kinetic exp...

Complex formation processes of sericin compounds with Ni 2+ , Cu Zn Co salts were studied. The possibility maximum extraction was determined when wastewater is purified by the proposed method, and developed purification method recommended for amino acid wastewater. By using coagulants Al2(SO4)3•18H2O FeCl3•6H2O flocculant PAA together sorbent, concentration in 0.75 mg/l, 0.5 amount kaolin bento...

the structure of the nonaaquayttrium (iii) bromate, [y(h2o)9](bro3)3, at low temperature (100 k) has been studied by means of single-crystal x-ray diffraction. crystallography shows a hexagonal unit cell, space group p63/mmc (no. 194) with z = 2, a = b = 11.7104(11) å, c = 6.6259(5) å and v = 786.90(12) å3 at 100 k. the hydrated trivalent yttrium(iii) ion forms a tricapped trigonal prism, in wh...

phenylalanine dehydrogenase (phedh; ec 1.4.1.20) is an important enzyme of amino acid dehydrogenases family that increasingly used as a valuable biocatalyst in neonatal screening kits and synthesis of l-phenylalanine. the goal of this literature was to find a suitable purification method for recombinant bacillus badius phedh by practical comparison between chromatographic and polyvinyl pyrrolid...

background: taq dna polymerase is a very important enzyme for molecular biological studies such as dna amplification and dna sequencing by the pcr. it is a standard enzyme that is used in 90% of molecular biology labs today. the aim of this study was to produce taq dna polymerase enzyme in e. coli by a reliable, practical, simple and low cost method.materials and methods: in this study, the taq...
