Stalactite of the abundance of limestone caves. The corresponding formation on the floor of the cave is known as a stalagmite. The most common stalactites are speleothems, which occur in limestone caves. They form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is the chief form of calcium carbonate rock which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution in underground caverns. The chemical formula for this reaction is: This solution travels through the rock until it reaches an edge and if this is on the roof of
Calcium acetate/magnesium carbonate of phosphorus resulting in increased serum phosphorus levels. This may worsen the overproduction of parathyroid hormone (hyperparathyroidism), and may lead to renal osteodystrophy, calcification of blood vessels and is associated with cardiovascular mortality (the so-called chronic kidney disease-mineral and bone disorder, CKD-MBD). In addition to dialysis therapy and dietary restrictions, a pharmaceutical therapy to lower serum phosphorus levels is recommended. Calcium acetate/magnesium carbonate is taken orally together with the meal. Calcium acetate and magnesium carbonate compounds bind phosphorus derived from food thereby forming indigestible phosphate salts in the intestine that are subsequently excreted with the faeces. The aim of the
