Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.
Oxalic acid has an oral LD Lo (lowest published lethal dose) of 600 mg/kg. [65] It has been reported that the lethal oral dose is 15 to 30 grams. [66] The toxicity of oxalic acid is due to kidney failure caused by precipitation of solid calcium oxalate. [67] Oxalate is known to cause mitochondrial dysfunction. [68]
The list of high oxalate foods should be changed. The standard in science is to list mg of oxalate per 100g of food. There are different methods for determining the soluble and insoluble oxalates, and such present compounds are expressed as a number in mg per 100g of the plant material.
Kidney stones are caused by high levels of the minerals calcium, oxalate, and phosphorus in urine.These minerals are normally found in urine and do not cause problems at low levels. However ...
Oxalobacter formigenes is a Gram negative oxalate-degrading anaerobic bacterium that was first isolated from the gastrointestinal tract of a sheep in 1985. [1] To date, the bacterium has been found to colonize the large intestines of numerous vertebrates, including humans, and has even been isolated from freshwater sediment. [2]
It is clear, however, that consuming foods high in oxalate – and in turn their effect on calcium absorption – is a more significant concern for people with oxalate kidney stones, which occur when there is too much oxalate in the urine. These people especially should reduce their oxalate intake and increase their calcium intake. [16]
