Contribution of dietary oxalate to urinary oxalate excretion [PDF]
Kidney International, 2001 The amount of oxalate excreted in urine has a significant impact on calcium oxalate supersaturation and stone formation. Dietary oxalate is believed to make only a minor (10 to 20%) contribution to the amount of oxalate excreted in urine, but the validity of the experimental observations that support this conclusion can be questioned.

Nature Reviews Nephrology, 2022
Oxalate homeostasis is maintained through a delicate balance between endogenous sources, exogenous supply and excretion from the body. Novel studies have shed light on the essential roles of metabolic pathways, the microbiome, epithelial oxalate transporters, and adequate oxalate excretion to maintain oxalate homeostasis.

DIETARY OXALATE LOADS AND RENAL OXALATE HANDLING
Journal of Urology, 2005Dietary 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.

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.

Oxalate Urolithiasis: Significance of Serum and Urinary Oxalate
Urologia Internationalis, 2010With a new enzymatic test using oxalate oxidase, serum and urinary oxalate can easily and quickly be determined. Serum oxalate in females was significantly higher than in males (39.5 µmol/l, 30.8 µmol/l). Increased serum levels were found only in male patients. Urinary excretion did not reveal sex-dependant differences in healthy persons.

Conductivometric determination of urinary oxalate with oxalate decarboxylase
Urological Research, 1982An enzymatic method for determination of urinary oxalate is described: the acidified urine samples are extracted with chloroform. This manipulation improves the blank values considerably. 1 ml of extracted urine is incubated with oxalate decarboxylase. The CO2 released from the medium is absorbed by Sr(OH)2.

Oxalate binding proteins in calcium oxalate nephrolithiasis
Urological Research, 2003The 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.

[Analysis of oxalic acid and oxalates].
Zeitschrift fur Urologie und Nephrologie, 1980It is reported on individual methods for the estimation of the oxalic acid in body fluids, particularly in the urine. The case in question is a survey of the oxalate estimation methods, which, however, has no pretensions to completeness. The at present most actualestimation methods are brought somewhat more in detail.
