Finally, P-31 NMR spectroscopy showed that Ca2+ bound to the phosphate group in anionic phospholipids at physiological concentrations, thus neutralizing the negative charge of phospholipids. Rather than initiating CD3 phosphorylation, this regulatory pathway of Ca2+ has a positive feedback effect on ...
Penczek and co- workers first investigated the hydrolytic degradation kinetics of poly(methyl ethylene phosphate) and poly(trimethylene phosph- ate) by direct titrimetric and NMR methods21. They found that the hydrolysis rates of the polymers were comparable to those of small molecule model ...
The chemiluminescent compounds comprise a luciferin ring system and an exocyclic enol phosphate group where the position on the luciferin ring system adjacent to the double bond is disubstituted. The chemiluminescent compounds are useful alone or within compositions containing a cationic aromatic compound ...

Answer to: Organic phosphate groups occur commonly in biological molecules. Calculate formal charges on the four O atoms in the methyl phosphate...
For the SPI coating, the PDA/PEG-coated glass was immersed in primary-amine-surface-functionalized SPCM solution (0.5 mg ml–1in phosphate-buffered saline (PBS), pH 8.5) under room temperature for 24 h. For the HPG/PEG coating and PEI coating, the PDA/PEG-coated substrate was ...

(b) Schematic illustration and characteristics of a three-dimensional (3D) interconnected structure of a 2-hydroxyethyl methacrylate phosphate (HEMAP) hydrogel membrane [255]. (b1) The space-charged HEMAP hydrogel membrane with interconnected nanopores. (b2) A free-standing and high-transmittance ...
S1). The interaction with Mg2+ must involve the exposed phosphate group on PA lipids and not the MSPs, since Mg2+ did not have an effect on POPC and POPS Nanodiscs, which also contain MSPs. Furthermore, the data suggest that Mg2+ also does not have a significant interaction with the ...
a Molecular representations of the folded and unfolded DNA hairpin with the phosphate, sugar, and base moieties colored in red, pink, and white, respectively; magenta and green spheres indicate the acceptor and donor dyes within the 5′-3′ FRET-labeled hairpin. The positively charged and ...
