Magnetic Structure of Manganese Pyrophosphate and Copper Pyrophosphate
Canadian Journal of Physics, 1972 The magnetic structures of antiferromagnetic manganese pyrophosphate and copper pyrophosphate have been determined by single crystal neutron diffraction techniques. There have been two previous determinations of the structure of manganese pyrophosphate.

THE OCCURRENCE OF PYROPHOSPHATE IN BONE
The Journal of Bone and Joint Surgery. British volume, 1958 A small proportion of the total phosphate in normal bone salt occurs in the form of pyrophosphate. The deposit formed in vitro on incubation of rachitic cartilage with a calcifying medium does not contain pyrophosphate unless ATP is added to the medium, in which case the proportion of pyrophosphate is of the same order as that found in normal bone.

Lancet, The, 1970 The concentration of inorganic pyrophosphate (I.P.P.) has been determined in the plasma, urine, and synovial fluid of patients with pyrophosphate arthropathy (chondrocalcinosis articularis or pseudogout). The concentrations of I.P.P.

American Journal of Clinical Pathology, 1975
A scanning electron microscopic study of six cases of pyrophosphate arthropathy has been conducted. In the majority of cases the crystals were rectangular. In some cases giant crystals were present. In one case, the crystals were pyramidal. It is concluded that many geometrically different forms of calcium pyrophosphate crystal exist and that the ...

Chemosensors for Pyrophosphate
Accounts of Chemical Research, 2008The selective detection of the anion pyrophosphate (PPi) is a major research focus. PPi is a biologically important target because it is the product of ATP hydrolysis under cellular conditions, and because it is involved in DNA replication catalyzed by DNA polymerase, its detection is being investigated as a real-time DNA sequencing method. In addition,

Soluble enzymes from sage (Salvia officinalis) and tansy (Tanacetum vulgare), which catalyze the cyclization of geranyl pyrophosphate and the presumptive intermediate linalyl pyrophosphate to the (+) and (-) enantiomers, respectively, of 2-bornyl pyrophosphate, were employed to evaluate mechanistic alternatives for the pyrophosphate migration in ...

Alternative photophosphorylation, inorganic pyrophosphate synthase and inorganic pyrophosphate
Photosynthesis Research, 1995This minireview in memory of Daniel I. Arnon, pioneer in photosynthesis research, concerns properties of the first and still only known alternative photophosphorylation system, with respect to the primary phosphorylated end product formed. The alternative to adenosine triphosphate (ATP), inorganic pyrophosphate (PPi), was produced in light, in ...

Phosphoribosyl pyrophosphate and the measurement on inorganic pyrophosphate in plant tissues
Planta, 1989This work provides further evidence that plants contain appreciable amounts of inorganic pyrophosphate (PPi), and that breakdown of phosphoribosyl pyrophosphate (PPRibP) does not contribute significantly to the PPi detected in plant extracts. Inorganic pyrophosphate in extracts of the roots of Pisum sativum L., clubs of the spadices of Arum maculatum L.

P(1)P(2)-Dicholesteryl and tetracholesteryl pyrophosphate have been obtained from the corresponding phosphorochloridates, and by treatment of the phosphates with dicyclohexylcarbodi-imide. These compounds are different from the di- and tetra-cholesteryl pyrophosphates previously reported.

Calcium pyrophosphate and pseudogout
Arthroscopy, 1985Abstract Calcium pyrophosphate deposition disease (CPDD) is a condition in which calcium pyrophosphate dihydrate crystals are deposited in joint articular cartilage, menisci, and synovium. The main clinical presentations of CPDD are chondrocalcinosis—calcification of cartilage, pseudogout—acute joint inflammation due to crystal ...
