IDENTIFICATION AND USE: White amorphous, or crystaline powder. It is odorless and tasteless. It is practically insoluble in alcohol, and acetic acid, and soluble in dilute hydrochloric acid, and nitric acid. Slightly soluble in water. It is used in the manufacture of fertilizers, phosphate compounds, manufacture of milk glass, polishing and dental powders, porcelains, pottery, enameling; clarifying sugar syrups; in animal feeds; as noncaking agent; in textile industry. It is used as a stabilizer in plastics; in meat tenderizers; in food as a buffer and used in medical applications as a calcium replenisher. It veterinary medicine it is used as a dietary supplement and an antacid. It is used in the manufacture of luminescent materials. HUMAN EXPOSURE AND TOXICITY: Tricalcium phosphate is not irritating and toxic doses by ingestion would have to be more than 2 g/kg. Skin sensitization is unusual. Aspiration or inhalation could cause chemical pneumonitis. Implantation of material will cause foreign body reaction. Tricalcium phosphate is contraindicated in treatment of hypocalcemia with hyperphosphatemia which may occur in hypoparathyroidism and renal failure. ANIMAL STUDIES: Tricalcium phosphate exhibited no teratogenic effect in developing chicken embryos.

Occurs in nature as the minerals: oxydapatit, voelicherite, whitlockite.

A - Alimentary tract and metabolism

QA - Alimentary tract and metabolism

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues. Phosphate exerts a modifying influence on calcium concentrations, a buffering effect on acid-base equilibrium, and has a major role in the renal excretion of hydrogen ions. /Phosphate/

Calcium phosphate reacts with acid in the stomach to raise the pH. In toothpaste it provides a source of calcium and phosphate ions to support remineralization of the teeth. As a supplement it provides a source of calcium and phospate, both of which are important ions in bone homeostasis.

The phosphate ions in calcium phosphate likely react with hydrochloric acid in the stomach to neutralize the pH. In toothpaste and in systemic circulation, calcium phosphate provides a source of calcium and phosphate ions to support remineralization of the teeth and bone homeostasis respectively. The increase in plasma calcium reduces calcium flux from osteocyte activity by reducing the secretion of parathyroid hormone (PTH). Calcium does this by stimulating a G-protein coupled calcium receptor on the surface of parathyroid cells. The reduction in calcium flux increases the amount of calcium deposited in bone resulting in an increase in bone mineral density. The reduction in PTH secretion also reduces the amount of vitamin D metabolized to its active form, calcidiol. Since calcidiol increases the expression of calcium dependent ATPases and transient receptor potential cation channel subfamily V member 6 (TRPV6) both of which are involved in calcium uptake from the gut, a reduction in calcidiol results in less calcium absorption. Additionally, TRPV5, the channel responsible for calcium reabsorption in the kidney, is downregulated when PTH secretion is reduced thus increasing calcium excretion via the kidneys. Another hormone, calitonin, is likely involved in the reduction of bone resorption during periods of high plasma calcium.

/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. Transport of phosphate from the gut lumen is an active, energy-dependent process that is modified by several factors. ... Vitamin D stimulates phosphate absorption, an effect reported to precede its action on calcium ion transport. In adults, about two thirds of the ingested phosphate is absorbed, and that which is absorbed is almost entirely excreted into the urine. In growing children, phosphate balance is positive. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/
