title: Retardation of calcium oxalate formation by polyacidic peptides.
abstract: The polycarboxylic amino acids were examined as possible retarding agents in the precipitation of calcium oxalate. The effect was observed by continuous determination of the concentration of calcium ions in a mimic urine solution. Both polyglutamic and polyaspartic acids, when used in 5 to 100 ppm concentrations, significantly retarded calcium oxalate precipitation.
