  2. Pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Pyrophosphate

    The pyrophosphate bond is also sometimes referred to as a phosphoanhydride bond, a naming convention which emphasizes the loss of water that occurs when two phosphates form a new P−O−P bond, and which mirrors the nomenclature for anhydrides of carboxylic acids.

  3. H+, Na+-translocating pyrophosphatase family - Wikipedia

    en.wikipedia.org/wiki/H+,_Na+-translocating...

    The plant enzymes probably pump one H + upon hydrolysis of pyrophosphate, thereby generating a proton motive force, positive and acidic in the tonoplast lumen. They establish a pmf of similar magnitude to that generated by the H +-translocating ATPases in the same vacuolar membrane. The bacterial and archaeal proteins may catalyze fully ...

    The last one is pyrophosphate [P 2 O 7] 4−. The pyrophosphates are mostly water-soluble. The pyrophosphates are mostly water-soluble. Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5− k P 3 O 10 ] k − , where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10 ] 5− .

  5. Inorganic pyrophosphatase - Wikipedia

    en.wikipedia.org/wiki/Inorganic_pyrophosphatase

    Inorganic pyrophosphatase (or inorganic diphosphatase, PPase) is an enzyme (EC 3.6.1.1) that catalyzes the conversion of one ion of pyrophosphate to two phosphate ions. [1] This is a highly exergonic reaction, and therefore can be coupled to unfavorable biochemical transformations in order to drive these transformations to completion. [2]

  6. PFP (enzyme) - Wikipedia

    en.wikipedia.org/wiki/PFP_(enzyme)

    Diphosphate—fructose-6-phosphate 1-phosphotransferase also known as PFP is an enzyme of carbohydrate metabolism in plants and some bacteria.The enzyme (EC 2.7.1.90) catalyses the reversible interconversion of fructose 6-phosphate and fructose 1,6-bisphosphate using inorganic pyrophosphate as the phosphoryl donor:

  7. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    Inorganic phosphate can also be present as pyrophosphate anions [P 2 O 7] 4−, which give orthophosphate by hydrolysis: [P 2 O 7] 4− + H 2 O ⇌ 2 [HPO 4] 2−. Organic phosphates are commonly found in the form of esters as nucleotides (e.g. AMP, ADP, and ATP) and in DNA and RNA.

  8. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  9. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    The same reaction can also be catalyzed by pyrophosphate-dependent phosphofructokinase (PFP or PPi-PFK), which is found in most plants, some bacteria, archea, and protists, but not in animals. This enzyme uses pyrophosphate (PPi) as a phosphate donor instead of ATP. It is a reversible reaction, increasing the flexibility of glycolytic ...
