Pyrophosphate

In an example, 10 grams of ore gave 28.5 milligrams of magnesic pyrophosphate, which is equivalent to 0.18 per cent. of phosphoric oxide. ❋ Cornelius Beringer (1886)

Left off that image was a byproduct of this reaction: two linked phosphates (called a pyrophosphate), which are cleaved off as the sugar-phosphate-sugar bonding forms. ❋ Unknown (2010)

Common chemical bleaches include household chlorine bleach, a solution of approximately 3 – 6% sodium hypochlorite (NaClO), and oxygen bleach, which contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate, sodium percarbonate, sodium persulfate, tetrasodium pyrophosphate, or urea peroxide together with catalysts and activators, e.g. tetraacetylethylenediamine and/or sodium nonanoyloxybenzenesulfonate. ❋ Unknown (2009)

He also found thiamine pyrophosphate to be a co-enzyme, which Severo ❋ Unknown (2010)

The Swedes would add one base of DNA at a time first A then C then G then T and, starting with the release of pyrophosphate, use a clever chemical domino effect involving an enzyme called luciferase, extracted from fireflies, to turn the chemical cue into a pulse of light. ❋ Kevin Davies (2010)

The amount of pyrophosphate, and thus the amount of light, released is directly proportional to the number of bases incorporated. ❋ Kevin Davies (2010)

The idea was to focus on a small molecule by-product, pyrophosphate, that was produced every time a new base was incorporated into a DNA chain. ❋ Kevin Davies (2010)

In the wake of the Twinkie defense, a representative of the ITT-owned Continental Baking Company asserted that the notion that overdosing on the cream-filled goodies could lead to murderous behavior was "poppycock" and "crap" -- apparently two of the artificial ingredients in Twinkies, along with sodium pyrophosphate and yellow dye -- while another spokesperson for ITT couldn't believe "that a rational jury paid serious attention to that issue." ❋ Unknown (2009)

A different colored balloon for every ribonucleotide and a puff of smoke for every pyrophosphate cleavage ... science entertainment at its best. ❋ Unknown (2006)

The latter case arises because the desired reaction is linked to a exothermic reaction, usually release of pyrophosphate i.e. ❋ Unknown (2006)

French Fries: Potatoes, partially hydrogenated soybean oil, natural flavor (beef, wheat and dairy sources), dextrose, sodium acid pyrophosphate (to preserve natural color). ❋ Unknown (2006)

We went on to propose that nitric oxide reacts with heme iron to alter the configuration of the catalytic binding site for GTP and promote the conversion of GTP to cyclic GMP and pyrophosphate. ❋ Unknown (1999)

From his early studies of the mechanisms of the enzymatic synthesis of coenzymes and inorganic pyrophosphate, he extended his interest to the biosynthesis of the nucleic acids, particularly DNA. ❋ Unknown (1959)

TEPP which is teta ethyl pyrophosphate is a very quick acting material but doesn't last. ❋ Unknown (N/A)

To the filtrate, ammonia and magnesia mixture are added, and the magnesium pyrophosphate separated and weighed with the usual precautions. ❋ W. J. Atkinson Butterfield (N/A)

Several organic phosphorus compounds, including hexaethyl tetraphosphate, tetraethyl pyrophosphate, and parathion, have also been developed. ❋ Unknown (N/A)

Residues of hexaethyl tetraphosphate and tetraethyl pyrophosphate persist for only a short time and residues of parathion drop to a low level within 10 to 14 days after application. ❋ Unknown (N/A)

In preliminary tests two or three applications of tetraethyl pyrophosphate (20 percent), 3/4 pint per 100 gallons of water, have given promising results in controlling the periodical cicada. ❋ Unknown (N/A)

Crystals may be obtained by heating di-calcium pyrophosphate, Ca_2P_2O_7, with water under pressure. ❋ Various (N/A)
