There is a continuous high urinary oxalate excretion in primary hyperoxaluria. Glycine is a metabolic precursor of oxalate, and the relative importance of the alternative metabolic pathways from glycine to oxalate have been studied in vivo using (1-13C) glycine and (2-13C) glycine. The results indicate that the main metabolic sequence is glycine → glyoxylate oxalate but that there is also a subsidiary contribution through the sequence glycine → serine → ethanolamine → glycolic aldehyde → glycolate glyoxylate → oxalate.
The metabolism of glyoxylate has been investigated in vitro in some human tissues. Kidney tissue from two patients with primary hyperoxaluria
