Phosphoric Acid Versus Biogenic Mineralization of Hydroxyapatite and Carbonate Apatite in Relation to Infection‐Induced Urinary Stones: Physical, Chemical and Microbiological Aspects

open access: yesChemPlusChem, Volume 90, Issue 5, May 2025.
Phosphoric acid is used in various products like food, sweets, beers, and soft drinks. Higher phosphoric acid concentration in urine accelerates the formation of carbonate apatite and hydroxyapatite, which are key components of infection urinary stones, a negative effect. However, the amount of these solid phases is smaller, which is beneficial.
