The monolayer-forming, human choriocarcinoma cell line, BeWo, was used to study the mechanisms of monocarboxylic acid transport across the human trophoblast. Benzoic acid, acetic acid, and lactic acid were used as markers for monocarboxylic acid carrier-mediated transport. The uptake of benzoic acid by BeWo cells was saturable (K(t) = 0.6 +/- 0.3 mM) at higher concentrations and significantly i...

Six strains were isolated from Lake Akşehir (Konya-Turkey) and identified as Rhodopseudomonas palustris on the basis of physiological and morphological characteristics. The strains grew phototrophically on a variety of aromatic compounds (under illuminated anaerobic conditions), namely, benzoate, hippurate, benzyl alcohol, 2-amino benzoic acid, phloroglucinol, phenylacetic acid, catechol, pyrid...

The coordination behavior of three ligand precursors 2-[(2- pyridinylmethyl)amino]acetic acid hydrochloride, 4-[(2- pyridinylmethyl)amino]benzoic hydrochloride and 4-{[2-(pyridin-2- ylmethylamino)ethylamino]methyl}benzoic HL1?HCl- HL3?HCl, respectively, in copper(II) complexes is described. were characterized by elemental analysis, ESI mass spectrometry IR spectroscopy, as well X-ray structural...

The purpose of this study was to evaluate the effects of feeding pigs with inulin and/or benzoic acid on post-weaning diarrhoea (PWD), indices of fermentation in the gastrointestinal tract, and production in pigs experimentally infected with an enterotoxigenic strain of Escherichia coli (ETEC). Forty-eight entire male pigs (Large White×Landrace) aged 21 ± 3 days of age and weighing 4.97 ± 0.08 ...

The asymmetric unit of the title compound, C(12)H(12)N(2)·C(7)H(7)NO(2), contains two 3-amino-benzoic acid mol-ecules and two 1,2-bis-(4-pyrid-yl)ethane mol-ecules. In the two 1,2-bis-(4-pyrid-yl)ethane mol-ecules, the dihedral angles between the pyridyl rings are 2.99 (9) and 46.78 (8)°. In the crystal, the mol-ecules associate through amine and carboxyl group N-H⋯O=C inter-actions between one...

In the crystal structure of the title 1:1 adduct, C(12)H(12)N(2)·C(8)H(9)NO(2), the 4-amino-3-methyl-benzoic acid mol-ecules and 1,2-bis-(4-pyrid-yl)ethane mol-ecules are linked by inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds, forming a two-dimensional supra-molecular network parallel to (001). In the 1,2-bis-(4-pyrid-yl)ethane mol-ecule, the two pyridine rings are twisted to each othe...

Hammett constants (σ) can be important factor to understanding substitution and position effects on benzoic acid. This report describes a computational study of ∆G◦ and σ for six substituted benzoic acid (X= F,Cl ,OH ,NH2 ,CN,NO2 )and phenylacetic acid substituted (X=OH ,NH2 ) at para and meta positions ingas and aqueousphases by DFT method and comparesit to available experimental and theoretic...

The coupled feeding of sarcosine (N-methylglycine) and benzoic acid, like the coupled feeding of glycine and benzoic acid, results in the excretion of hippuric acid at a rate greater than that when benzoic acid is fed alone (1). When sarcosine containing an excess of N16 is fed to rats, the isotope content of the amino acids of the tissues is almost identical with that of animals fed glycine co...

The title compound, C7H2ClF3O2, was prepared by the chlorination of 3-amino-2,4,5-trifluoro-benzoic acid. The carboxyl group is twisted relative to the benzene ring by 6.8 (1)°. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules into typical centrosymmetric carb-oxy-lic acid dimers. These dimers are arranged into sheets parallel to (-103).
