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.
Within the field of biochemistry, 4-amino-5-hydroxymethyl-2-methylpyrimidine (HMP) also known as toxopyrimidine together with its mono phosphate (HMP-P) and pyrophosphate (HMP-PP) esters are biogenetic precursors to the important biochemical cofactor thiamine pyrophosphate (TPP), a derivative of thiamine (vitamin B 1).
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]
Phytomining, sometimes called agromining, [1] is the concept of extracting heavy metals from the soil using plants. [2] Specifically, phytomining is for the purpose of economic gain. [ 3 ] The approach exploits the existence of hyperaccumulators , proteins or compounds secreted by plants to bind certain metal ions.
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).
A biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. [1]
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 ...
There must be phosphorus in the soil, but the plant must also absorb the phosphorus. Phosphorus uptake is limited by the chemical form of the phosphorus. A large portion of phosphorus in soil is in chemical compounds that plants can't absorb. [9] Phosphorus must be present in soil in specific chemical arrangements to be usable as plant nutrients.
