Sorry, no etymologies found.
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.
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.
He also found thiamine pyrophosphate to be a co-enzyme, which Severo
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.
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.
The amount of pyrophosphate, and thus the amount of light, released is directly proportional to the number of bases incorporated.
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.
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."
A different colored balloon for every ribonucleotide and a puff of smoke for every pyrophosphate cleavage ... science entertainment at its best.
The latter case arises because the desired reaction is linked to a exothermic reaction, usually release of pyrophosphate i.e.
