2025
Source: Pokhrel, A., et al. Assaying for Inorganic Polyphosphate in Bacteria. J. Vis. Exp. (2019).This video demonstrates a colorimetric assay to measure inorganic polyphosphate (polyP) in bacterial samples. The procedure involves enzymatically converting polyP into free phosphate, which then reacts with molybdate and ascorbic acid to produce a blue-colored complex. By comparing the absorbance of this complex to a standard curve of known phosphate concentrations, the polyP content in bacterial...

A two dimensional model material of discotic zirconium phosphate was developed. The inorganic crystal with lamellar structure was synthesized by hydrothermal, reflux, and microwave-assisted methods. On exfoliation with organic molecules, layered crystals can be converted to monolayers, and nematic liquid crystal phase was formed at sufficient concentration of monolayers.

The phosphate buffer system is a critical biological mechanism for maintaining pH stability in the body. This system operates primarily through two components: sodium dihydrogen phosphate (NaH2PO4), which acts as a weak acid, and sodium hydrogen phosphate (Na2HPO4), which serves as a weak base. Sodium dihydrogen phosphate does not fully dissociate in neutral or acidic solutions. When a strong base, such as sodium hydroxide (NaOH), is introduced into the solution, sodium dihydrogen phosphate...

This protocol describes the synthesis and solution deposition of inorganic nanocrystals layer by layer to produce thin film electronics on non-conductive surfaces. Solvent-stabilized inks can produce complete photovoltaic devices on glass substrates via spin and spray coating following post-deposition ligand exchange and sintering.
FAQs
pH controls the distribution of inorganic phosphate among interconvertible protonation states. Because these forms can shift as acidity changes, the phosphate pool can resist changes in pH and function as a buffer. The same chemical flexibility also affects how phosphate participates in biological reactions, including the transfer of phosphate groups during phosphorylation.
Phosphate-group transfer connects inorganic phosphate with reactions involving sugars, proteins, ADP, and ATP. Adding or removing a phosphate group can alter a molecule's chemical state or regulatory behavior, while phosphate incorporation into ADP contributes to ATP production. These linked reactions help cells coordinate energy use with metabolic activity.
Organisms must regulate phosphate availability so that energy production, biosynthesis, and mineral use remain balanced. Transport processes help move phosphate to locations where it is needed, while homeostatic control maintains appropriate phosphate pools. Studying these systems reveals how biology manages both immediate metabolic demands and longer-term mineral resources.
Phosphate concentration measurements provide information about cellular metabolism, nutrient cycling, water quality, and physiological disorders. In cells, changes may indicate altered metabolic activity or energy balance. In environmental systems, measurements help track nutrient movement and water conditions, while physiological measurements can support investigation of disrupted phosphate regulation.
Phosphate supplies structural and chemical components needed to form nucleic acids and phospholipids. Its involvement links phosphate availability to the production of genetic material and membrane-associated molecules. Consequently, studying phosphate pools can help connect nutrient status with biosynthetic capacity, cellular structure, and the maintenance of essential biological materials.
Phosphate contributes to skeletal mineralization, making its controlled availability important for biological mineral resources as well as cellular chemistry. Research on phosphate therefore spans metabolism, tissue mineralization, and organism-level regulation. Comparing these roles helps explain why phosphate homeostasis must coordinate energy-related reactions with the formation and maintenance of mineralized structures.
