In this work, we studied the effect of carboxylic acid on the rheological properties of a high-alumina cement mortar (CH45) produced by the Algerian firm REFRACTAL.The investigated properties are setting time, water consumption, electrical conductivity, pH, density and the compressive strength. The results show a setting time of about 200 min for the acid...

The micro-alga Chlorella pyrenoidosa expresses an enzymatic activity that cleaves the 13-hydroperoxide derivatives of linoleic acid [13-hydroperoxy-9(Z),11(E)-octadecadienoic acid, 13-HPOD] and linolenic acid [13-hydroperoxy-9(Z),11(E),15(Z)-octadecatrienoic acid, 13-HPOT] into volatile C(5) and non-volatile C(13) oxo-products. This enzymic activity initially was attributed to a hydroperoxide l...

The carboxylic ester hydrolases (CEHs) are enzymes that hydrolyze an ester bond to form a carboxylic acid and an alcohol. They are one of the enzyme groups that are most explored industrially for their applications in the food, flavor, pharmaceutical, organic synthesis, and detergent industries. We classified CEHs into families and clans according to their amino acid sequences (primary structur...

Molecular dynamics simulations are used to investigate the interfacial properties of molecules related flavours Scotch whisky, in ethanol/water solutions with different values alcohol-by-volume (ABV). The propensity flavour accumulate at liquid-vapour interface is linked evaporation those into head space, and consequently their perception when nosing or tasting. simulation approach first valida...

vilsmeier several diamide derivatives containing 2-chloroquinoline scaffolds were synthesized via ugi reaction of 2-chloroquinoline-3-carboxaldehydes, amines, carboxylic acids and isocyanides. the diversity of these quinolinyl ugi-adducts was increased by using 2-chloroquinoline-3-carboxylic acids as a source of acid. among them, compounds 2d, 2n, 2p, 4a, 4c and 4e displayed moderate to good an...

In ethanol-water (v:v = 1:1), a new Ni(II) complex, [Ni(L)2(H2O)2] (1) (HL 6-phenylpyridine-2-carboxylic acid) was synthesized using acid, NaOH and Ni(CH3COO)2.4H2O. The structure of complex 1 has been determined by elemental analysis single crystal X-ray diffraction. shows that contains one ion, two L ligands coordinated water molecules. 1, the ion is six-coordinated to O atoms N from molecule...

L-Azetidine-2-carboxylic acid is the naturally occurring lower homologue of L-proline. Reticulocytes from anemic rabbits incubated with DL-[14-C]azetidine-2-carboxylic acid synthesized radiolabeled hemoglobin, which when isolated from cell lysates co-chromatographed with unlabeled hemoglobin on Sephadex G-100 columns. Amino acid analysis of hemoglobin from reticulocytes incubated with DL-[14-C]...
