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.

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.

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.

[Oxalate as a promoter in calcium oxalate nephrolithiasis].
Hinyokika kiyo. Acta urologica Japonica, 1992Oxalate transports on membranes of red blood cell, intestinal epithelium and proximal tubule cell were reviewed, and the new findings about oxalate transport across these membranes are reported. Red blood cell oxalate influx rate in a group of recurrent calcium oxalate stone formers was significantly higher than that of a control group.
