3 often prepared as the tributylammonium ((C 4 H 9) 3 NH +) or tetrabutylammonium ((C 4 H 9) 4 N + salt. The anion features phosphorus(V) bonded to three tetrachlorocatecholate (C 6 Cl 4 O 2− 2) ligands. This anion can be resolved into the axially chiral enantiomers, which are optically stable (the picture shows the Δ enantiomer).
Pyrophosphorolysis is the reverse of the polymerization reaction in which pyrophosphate reacts with the 3′-nucleosidemonophosphate (NMP or dNMP), which is removed from the oligonucleotide to release the corresponding triphosphate (dNTP from DNA, or NTP from RNA). The pyrophosphate anion has the structure P 2 O 4− 7, and is an acid anhydride ...
For example, treatment of Bu 4 NOH with disodium pyrophosphate, Na 2 H 2 P 2 O 7, gives (Bu 4 N) 3 [HP 2 O 7], which is soluble in organic solvents. [2] Similarly, neutralization of Bu 4 NOH with hydrofluoric acid affords a relatively water-free Bu 4 NF. This salt dissolves in organic solvents and is useful in desilylation. [3]
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
At physiological pH's, pyrophosphate exists as a mixture of doubly and singly protonated forms. When molten, pyrophosphoric acid rapidly converts to an equilibrium mixture of phosphoric acid, pyrophosphoric acid and polyphosphoric acids. The percentage by weight of pyrophosphoric acid is around 40% and it is difficult to recrystallise from the ...

A man who ate the carnivore diet had cholesterol of 1,000 and developed yellow lumps on his hands, deposits of excess cholesterol under his skin.
Abiotic stresses to plants, including wounding and excessive high-light exposure, lead to an increase in MEcPP accumulation in chloroplasts. Transported from the chloroplast to the plant cell nucleus , MEcPP engages in retrograde signalling that leads to the specific induction of nuclear-encoded stress-response genes.
