Chemical Information
FooDB NameCalcium oxalate
DescriptionCalcium 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 .

EmeticAn agent that induces vomiting, playing a biological role in expelling toxins from the body. Therapeutically, it is used to treat poisoning, overdose, or gastrointestinal obstruction. Key medical uses include managing drug toxicity and aiding in stomach pumping procedures.DUKE
InflammatoryAn agent that triggers inflammation, a biological response to injury or infection. It plays a role in immune response, but excessive inflammation can be harmful. Therapeutically, inflammatory agents are used in vaccine development and cancer treatment to stimulate immune response. Key medical uses include immunotherapy and vaccination, where controlled inflammation enhances immune response to fight diseases.DUKE
Laxative50503 An agent that stimulates bowel movements, relieving constipation by softening stool or increasing intestinal motility. Therapeutically, laxatives are used to treat constipation, prepare the bowel for medical procedures, and manage certain medical conditions, such as irritable bowel syndrome.DUKE
LithogenicAn agent that promotes the formation of calculi (kidney stones), playing a role in certain biological processes. Therapeutically, it has limited applications, but is used in research to study kidney stone formation. Medically, understanding lithogenic factors is crucial in preventing and managing kidney stone disease, allowing for targeted interventions to reduce stone formation and recurrence.DUKE
