The title compound, poly[aqua(μ2-1H-imidazole-4-carboxylato-κ3N3,O:O′)hemi(μ2-oxalato-κ4O1,O2:O1′,O2′)cadmium(II)], [Cd(C4H3N2O2)(C2O4)0.5(H2O)]n, exhibits a two-dimensional network. The CdIIcation is coordinated to one N atom and two carboxylate O atoms from two 1H-imidazole-4-carboxylate (Himc) ligands, two carboxylate O atoms from the bridging oxalate anion and one ligated water molecule; these six donor atoms form a distorted octahedral configuration. The oxalate anion lies on a centre of inversion. The Himc ligands connect the CdIIcations to form –Cd–Himc–Cd–Himc–Cd– zigzag chains, with a

Abstract:
Lactoferrin binds two Fe3+ and two CO^{2-}_{3} ions with high affinity. It can also bind other metal ions and anions. In order to determine the perturbations in the environments of the binding sites in the N and C lobes and elsewhere in the protein, the crystal structure of oxalate-substituted diferric mare lactoferrin has been determined at 2.7 Å resolution. The final model has a crystallographic R factor of 21.3% for all data in the resolution range 17.0–2.7 Å. The substitution of an oxalate anion does not perturb the overall structure of the protein, but produces several significant changes

The adipate and oxalate ions are located on centres of inversion. The Dy3+cation has a distorted tricapped trigonal–prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further e

Abstract:
To evaluate the possibility that an apical membrane conductive pathway for oxalate is present in the rabbit distal ileum, we studied oxalate ([14C]oxalate) and chloride (36Cl) uptake into brush-border membrane vesicles enriched 15- to 18-fold in sucrase activity. Voltage-sensitive pathways for oxalate and chloride were identified by the stimulation of uptake provided by an inwardly directed potassium diffusion potential in the presence of valinomycin. Additionally, outwardly directed oxalate (or chloride) gradients stimulated [14C]oxalate (or36Cl) uptake to a greater degree in the absence of v

Abstract:
Mice deficient for the apical membrane oxalate transporter SLC26A6 develop hyperoxalemia, hyperoxaluria, and calcium oxalate stones due to a defect in intestinal oxalate secretion. However, the nature of the basolateral membrane oxalate transport process that operates in series with SLC26A6 to mediate active oxalate secretion in the intestine remains unknown. Sulfate anion transporter-1 (Sat1 or SLC26A1) is a basolateral membrane anion exchanger that mediates intestinal oxalate transport. Moreover, Sat1-deficient mice also have a phenotype of hyperoxalemia, hyperoxaluria, and calcium oxalate s

Abstract Oxalate concentration differs in various daily consumed food products. The role of oxalic acid in the human body is very significant, as its compounds are responsible for the stability of biological membranes. However, insoluble calcium and magnesium oxalates can be accumulated in the body in the form of kidney stones. Oxalate concentration has been measured by high performance liquid, gas after derivatization and ion chromatography (IC). The most effective method for the simultaneous determination of oxalate and inorganic anions is ion chromatography with conductometric detection. He

Both techniques were compared to theoretical structures calculated using various levels of theory. With the use of IRMPD, frequencies were generated for each complex and compared to theoretical frequencies. Plausible structures for all complexes were found using the M-series of density functional levels of the theory when the 6-311+gd
