| FooDB Name | Calcium oxalate |
|---|
| Description | Calcium oxalate, also known as calcium oxalate monohydrate or calcium oxalic acid, belongs to dicarboxylic acids and derivatives class of compounds. Those are organic compounds containing exactly two carboxylic acid groups. Calcium oxalate is soluble (in water) and a moderately acidic compound (based on its pKa). Calcium oxalate can be found in a number of food items such as taro, ginkgo nuts, caraway, and sweet potato, which makes calcium oxalate a potential biomarker for the consumption of these food products. Calcium oxalate (in archaic terminology, oxalate of lime) is a calcium salt of oxalate with the chemical formula CaC2O4(H2O)x, where x can vary. All forms are colorless or white. The monohydrate occurs naturally as the mineral whewellite, forming envelope-shaped crystals, known in plants as raphides. The rarer dihydrate (mineral: weddellite) and trihydrate (mineral: caoxite) are also recognized. Calcium oxalates are as major constituent of human kidney stones, calcium oxalate is also found in beerstone, a scale that forms on containers used in breweries . |
