Myristyl Trimethyl Ammonium Bromide and Octadecyl

Dec 01, 2021Dynamin is a GTPase enzyme involved in membrane constriction and fission during endocytosis. Phospholipid binding via its pleckstrin homology domain maximally stimulates dynamin activity. We developed a series of surface-active small-molecule inhibitors, such as myristyl trimethyl ammonium bromide (MiTMAB) and octadecyltrimethyl ammonium bromide (OcTMAB), and we now show MiTMAB

The colorimetric detection of Pb2+ by using sodium

A simple, rapid colorimetric detection method for Pb 2+ in aqueous solution has been developed by using sodium thiosulfate (Na 2 S 2 O 3) and hexadecyl trimethyl ammonium bromide (CTAB) modified gold nanoparticles (Au NPs). Na 2 S 2 O 3 was added into the Au NP solution and thiosulfate ions (S 2 O 3 2−) were adsorbed on the surface of the Au NPs due to electrostatic interactions.

Why does bromide not react with water when methyl ammonium

Nov 20, 2021The key is comparing $mathrm{p}K_mathrm{a}$ values. A good resource for this is the Evans $mathrm{p}K_mathrm{a}$ table.Unfortunately, the table does not contain $ce{CH3NH3+}$, but in the section protonated nitrogen there is a value quoted for $ce{C2H5NH3+}$ — which is chemically similar enough to methyl ammonium to assume the $mathrm{p}K_mathrm{a}$ values to be essentially identical.
