DIETARY OXALATE LOADS AND RENAL OXALATE HANDLING

Journal of Urology, 2005
Dietary oxalate makes a significant contribution to urinary oxalate excretion and, thus, may have a role in calcium oxalate kidney stone formation. Studies have indicated that the ingestion of oxalate rich foods results in transient increases in plasma oxalate concentrations and urinary oxalate excretion.

Photochemical Aging of Guaiacol by Fe(III)-Oxalate Complexes in Atmospheric Aqueous Phase.

Environmental Science and Technology, 2018
Fe(III)-oxalate complexes are likely abundant in clouds, fogs and aerosol water. They are photoreactive and can act as an important source of reactive oxygen species (·OH, H2O2 and HO2·) in tropospheric aqueous phases. Although the mechanisms involved in

Oxalate binding proteins in calcium oxalate nephrolithiasis

Urological Research, 2003
The existence of several oxalate specific binding proteins have been demonstrated in human and rat kidney. These occur in both cortical and medullary cells and are distributed mostly in the subcellular organelles. About 1/3 of the total cellular oxalate binding was localised in the inner mitochondrial membrane while the rest was in the nucleus.

Direct Observation of C2O4•- and CO2•- by Oxidation of Oxalate within Nanogap of Scanning Electrochemical Microscope.

Journal of the American Chemical Society, 2018
Oxalate oxidation in the presence of different oxidized luminophores leads to the emission of light and has been studied extensively in electrogenerated chemiluminescence (ECL). The proposed mechanism involves the initial formation of the oxalate radical

Oxalate Formation Enhanced by Fe-Containing Particles and Environmental Implications.

Environmental Science and Technology, 2018
We used a single particle mass spectrometry to online detect chemical compositions of individual particles over four seasons in Guangzhou. Number fractions (Nfs) of all the measured particles that contained oxalate were 1.9%, 5.2%, 25.1%, and 15.5 ...

Glycinium oxalate

Acta Crystallographica Section C Crystal Structure Communications, 2001
In the title compound, C2H6NO2+.C2HO4-, the glycine molecule exists in the cationic form and the oxalic acid molecule in the mono-ionized state. The molecules aggregate into alternate columns of glycinium and semi-oxalate ions. The structure is stabilized by an extensive network of hydrogen bonds.

13C chemical shielding in oxalic acid, oxalic acid dihydrate, and diammonium oxalate

The Journal of Chemical Physics, 1975
13C chemical shielding tensors in three oxalates were investigated in order to determine the effects of protonation and conformation changes on the tensor elements and their orientations. The experimental results, together with those in the accompanying paper [R. G. Griffin and D. J. Ruben, J. Chem. Phys.

Calcium oxalate in plants: formation and function.

Annual Review of Plant Biology, 2005
Calcium oxalate (CaOx) crystals are distributed among all taxonomic levels of photosynthetic organisms from small algae to angiosperms and giant gymnosperms. Accumulation of crystals by these organisms can be substantial.
