calciumoxalát

Calcium oxalate is a chemical compound with the formula CaC2O4. It is a salt of calcium and oxalate. This compound is a white crystalline solid and is insoluble in water. Calcium oxalate is a common component of kidney stones, particularly the most common type, which are formed when calcium and oxalate crystals aggregate in the urine. It can also be found in plants, where it serves as a defense mechanism against herbivores. Some plants, like rhubarb and spinach, contain significant amounts of calcium oxalate. Ingesting large quantities of these plants can lead to irritation of the mouth and digestive tract due to the sharp, needle-like crystals. In industrial applications, calcium oxalate can be used as a precursor in the production of calcium carbonate. It is also used in some dental materials. The formation of calcium oxalate crystals in biological systems is influenced by factors such as diet, hydration levels, and certain medical conditions. While essential for bone health, excessive calcium intake in combination with high oxalate consumption can increase the risk of calcium oxalate stone formation.
