Abstract:
The effects of L-aspartic acid, alanine, and L-glutamic acid on the crystn. of Ca oxalate were followed by 2 methods. Glutamic acid (0-200 ppm) was added to solns. of CaCl2 which were subsequently mixed with solns. of Na2C2O4 to yield CaC2O4 pptn. At relatively high concns. of glutamic acid (20-200 ppm), the pptn. of Ca oxalate is retarded. However, at low concns., 2.5-20 ppm, oxalate pptn. is enhanced. The 2 independent methods yield well-correlated results. Both L-aspartic acid and alanine did not affect the pptn. of Ca oxalate. The results are discussed with respect to renal calculi formation.
