2. Calcium oxalate - Wikipedia

   en.wikipedia.org/wiki/Calcium_oxalate

   Calcium oxalate (in archaic terminology, oxalate of lime) is a calcium salt of oxalic acid with the chemical formula CaC 2 O 4 or Ca(COO) 2. It forms hydrates CaC 2 O 4 · n H 2 O , where n varies from 1 to 3.

3. Druse (botany) - Wikipedia

   en.wikipedia.org/wiki/Druse_(botany)

   A druse is a group of crystals of calcium oxalate, [1] silicates, or carbonates present in plants, and are thought to be a defense against herbivory due to their toxicity. . Calcium oxalate (Ca(COO) 2, CaOx) crystals are found in algae, angiosperms and gymnosperms in more than 215 fami

4. Whewellite - Wikipedia

   en.wikipedia.org/wiki/Whewellite

   Whewellite / ˈ h juː ə l aɪ t / is a mineral, hydrated calcium oxalate, formula Ca C 2 O 4 ·H 2 O. [6] Because of its organic content it is thought to have an indirect biological origin; this hypothesis is supported by its presence in coal and sedimentary nodules. However, it has also been found in hydrothermal deposits where a biological ...

5. Raphide - Wikipedia

   en.wikipedia.org/wiki/Raphide

   Raphides in Epipremnum Devil's ivy (600× magnification). Raphides (/ ˈ r æ f ɪ d i z / RAF-id-eez; singular raphide / ˈ r eɪ f aɪ d / RAY-fyde or raphis) are needle-shaped crystals of calcium oxalate monohydrate (prismatic monoclinic crystals) or calcium carbonate as aragonite (dipyramidal orthorhombic crystals), found in more than 200 families of plants.

6. Weddellite - Wikipedia

   en.wikipedia.org/wiki/Weddellite

   Weddellite, or calcium oxalate dihydrate, crystallises in a tetragonal system: the classic crystal shape is the eight-face bipyramid. Using bright field microscopy, the weddellite crystals are recognised easily by their shape, reminiscent of a postal envelope. More complex shapes of weddellite are possible; the dumbbell shape is not rare and ...

7. Oxalic acid - Wikipedia

   en.wikipedia.org/wiki/Oxalic_acid

   Rhubarb leaves contain about 0.5% oxalic acid, and jack-in-the-pulpit (Arisaema triphyllum) contains calcium oxalate crystals. Similarly, the Virginia creeper, a common decorative vine, produces oxalic acid in its berries as well as oxalate crystals in the sap, in the form of raphides. Bacteria produce oxalates from oxidation of carbohydrates. [16]

8. Bladder stone (animal) - Wikipedia

   en.wikipedia.org/wiki/Bladder_stone_(animal)

   Calcium oxalate stones form in an acidic to neutral urine. Two types naturally occur, calcium oxalate monohydrate, or whewellite (CaC 2 O 4 ·H 2 O), and calcium oxalate dihydrate, or weddellite (CaC 2 O 4 ·2H 2 O). Their appearance can be rough, smooth, spiculated (needle-like), or jackstone. Calcium oxalate stones form more readily in ...
