Sep-Pak Amino Propyl (NH2) Vac cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges ...
Cell - surface interactions: Given its positively charged nature, it may interact with negatively charged components on the cell surface, such as the phosphate groups in the phospholipid bilayer of the cell membrane or acidic residues on cell - surface proteins. This interaction could potentially mod...

It was already known that the chemical stability of MIL-125-NH2 is quite limited when exposed to acidic and basic conditions, which restricts activation processes to milder conditions. This often yields suboptimal results or requires MOFs metal doping for stability improvement [23]. This work ...
This is unanimous with previous works in which FA was identified as a precursor to form formate esters rather than as an acidic catalyst to accelerate the hydrogenolysis of 5-hydroxymethylfural to 2,5-dimethylfuran at relatively high temperature (>120°C).32, 33, 34 Thus, two possible ...
It takes place by mixing an acidic and a basic chemical entity together. It leads to a formation of a conjugate acid by the acceptance of a proton by the basic entity and a conjugate base by the donation of a proton by the acidic entity....

The Ac-His-dPhe-Arg-Trp-NH2 tetrapeptide is a nonselective melanocortin agonist and replacement of Arg in the tetrapeptide with acidic, basic or neutral amino acids results in reduced potency at the melanocortin receptor (MCR) isoforms (MC1R and MC3-5R). To determine the importance of the ...
In this study, a porous nanocontainer from UiO-66-NH2/CNTs nanocomposite with an excellent barrier characteristics was constructed through amine-functionalized Zr-based metal organic framework. The characterization of the prepared nano-materials were per
