The anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates. The pyrophosphate anion is abbreviated PPi and is formed by the hydrolysis of ATP into AMP in cells. This hydrolysis is called pyrophosphorolysis. The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate. Pyrophosphate is an osteotoxin (arrests bone development) and an arthritogen (promotes arthritis). It is also a metabotoxin (an endogenously produced metabolite that causes adverse health affects at chronically high levels). Chronically high levels of pyrophosphate are associated with hypophosphatasia. Hypophosphatasia (also called deficiency of alkaline phosphatase or phosphoethanolaminuria) is a rare, and sometimes fatal, metabolic bone disease. Hypophosphatasia is associated with a molecular defect in the gene encoding tissue non-specific alkaline phosphatase (TNSALP). TNSALP is an enzyme that is tethered to the outer surface of osteoblasts and chondrocytes. TNSALP hydrolyzes several substances, including inorganic pyrophosphate (PPi) and pyridoxal 5-phosphate (PLP), a major form of vitamin B6. When TSNALP is low, inorganic pyrophosphate (PPi) accumulates outside of cells and inhibits the formation of hydroxyapatite, one of the main components of bone, causing rickets in infants and children and osteomalacia (soft bones) in adults. Vitamin B6 must be dephosphorylated by TNSALP before it can cross the cell membrane. Vitamin B6 deficiency in the brain impairs synthesis of neurotransmitters which can cause seizures. In some cases, a build-up of calcium pyrophosphate dihydrate crystals in the joints can cause pseudogout.

ent-Copalyl diphosphate

[({[(2E)-5-[(1R,4aR,8aR)-5,5,8a-trimethyl-2-methylidene-decahydronaphthalen-1-yl]-3-methylpent-2-en-1-yl]oxy}(hydroxy)phosphoryl)oxy]phosphonic acid

C20H36O7P2 (450.1936166)


Ent-copalyl diphosphate, also known as (-)-copalyl diphosphoric acid or 5a,9a,10b-labda-8(20),13-dien-15-yl diphosphate, is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Thus, ent-copalyl diphosphate is considered to be an isoprenoid lipid molecule. Ent-copalyl diphosphate is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Ent-copalyl diphosphate can be found in a number of food items such as german camomile, sweet basil, eggplant, and cardoon, which makes ent-copalyl diphosphate a potential biomarker for the consumption of these food products.
