Sequences of Copolyesters by 1H NMR and 31P NMR Spectroscopy [PDF]

Polymer Journal, 1998
31P NMR and 1H NMR spectra of copolyesters containing phosphorus compounds, obtained by ester-exchange reaction, were studied. Poly(ethylene terephthalate) was used as the main component and poly(hydroquinone phenylphosphate), poly[bis(4-hydroxyphenyl)sulfonephenylphosphate], and poly[bis(4-hydroxyphenyl)sulfonemethylphosphate], as phosphorus compounds.

Development of a new and reliable assay for choline kinase using 31P NMR

Heliyon, 2019
Choline kinase catalyzes the conversion of choline to phosphocholine (PC) by transferring a phosphate group from adenosine triphosphate (ATP) as the first step in the biosynthetic pathway for the membrane phospholipid phosphatidylcholine, an essential ...

An intracellular pH gradient in the anammox bacterium Kuenenia stuttgartiensis as evaluated by (31)P NMR [PDF]

, 2009
The cytoplasm of anaerobic ammonium oxidizing (anammox) bacteria consists of three compartments separated by membranes. It has been suggested that a proton motive force may be generated over the membrane of the innermost compartment, the “anammoxosome ...

Potential Phosphorus Uptake Mechanisms in the Deep Sedimentary Biosphere

Frontiers in Marine Science, 2022
Our understanding of phosphorus (P) dynamics in the deep subseafloor environment remains limited. Here we investigate potential microbial P uptake mechanisms in oligotrophic marine sediments beneath the North Atlantic Gyre and their effects on the ...

Synthesis and Application in Polypropylene of a Novel of Phosphorus-Containing Intumescent Flame Retardant

Molecules, 2010
A novel phosphorus-containing triazine oligomer poly(2-morpholinyl-4-penta-erythritol phosphate-1,3,5-triazine) (PMPT) was synthesized as a kind of tri-component intumescent flame retardant (IFR). The chemical structure of PMPT was characterized by FTIR,
