A novel self-assembled nano micelle as a highly efficient artificial peroxidase based on hexadecyl trimethyl ammonium bromide and cytochrome c

A novel self-assembled nano micelle as a highly efficient artificial peroxidase based on hexadecyl trimethyl ammonium bromide and cytochrome c.

A novel artificial peroxidase (AP) with highly catalytic efficiency was designed using hexadecyl trimethyl ammonium bromide (CTAB, 3 mM) nano-micelles and bovine heart cytochrome c (Cyt c, 0.5 µM) in 100 mM, pH 8.0 phosphate buffer at 25°C. The catalytic rate (kcat) and Michaelis-Menten (Km) of the AP were determined to be 0.311 ± 0.013 s(-1) and 8.64 ± 0.6 µM. The catalytic efficiency was 0.03...

Hexadecyl Trimethyl Ammonium Bromide-Modified Montmorillonite as a Low-Cost Sorbent for the Removal of Methyl Red from Liquid-Medium

In this study, montmorillonite (MMT) modified by a cationic surfactant (Hexadecyltrimethyl ammonium bromide, HDTMA) was used as adsorbent to the removal of methyl red (MR) from aqueous solution. The effect of different parameters includes surfactant loading rate, contact time, pH, adsorbent dosage, and initial MR content was investigated on the sorption. The sorption capacity was increased by i...

THERMODYNAMIC STUDIES ON THE INTERACTION BETWEEN DODECYL TRIMETHYL AMMONIUM BROMIDE AND HISTONE H A

The thermodynamic parameters of interaction between calf thymus histone H A and dodecyl trimethyl ammonium bromide (DTAB), a cationic surfactant, in aqueous solutions of pH 3.2, 6.4 and 10.0 were measured over a wide range of DTAB concentrations by equilibrium dialysis at 27°C and 37°C and are discussed. The data are used to determine the free energy from the Wyman binding potential theore...

Effect of Hexadecyl Trimethyl Ammonium Bromide (C16TAB) as Cationic Surfactant on Contact Angle and Interfacial Tension of Carbonate Rocks and Oil

Biopolymer-surfactant Interactions: Binding Studies of Cetyltrimethyl Ammonium Bromide, Cetyl Pyridinium Bromide and Dodecyl Trimethyl Ammonium Bromide with Β-lactoglobulin

Binding studies of cationic detergents such as cetyltrimethyl ammonium bromide, Cetyl pyridinium bromide and dodecyl trimethyl ammonium bromide with β Lactoglobulin were carried out by equilibrium dialysis, ultraviolet difference and circular dichroism techniques at 25 C. Binding isotherms at pH 5·0, 7·0 and 9·0 show cooperative binding at all concentrations of detergents and the number of avai...
