Bovine intestine alkaline phosphatase (BIALP) is widely used as a signaling enzyme in sensitive assays such as enzyme immunoassay (EIA). In this study, we evaluated the effects of various aminoalcohols and amines on the activity of BIALP in the hydrolysis of p-nitrophenyl phosphate (pNPP) at pH 9.8, at 20 °C. The k(cat) values at 0.05 M diethanolamine, 0.1 M triethanolamine, and 0.2 M N-methyle...

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.

In this article, the electrochemical behavior of triethanolimine is described with a carbon paste electrode. A differential pulse voltammetric method was also developed for the determination of triethanolamine as an application to electroanalysis at a carbon paste electrode. The resultant voltammograms have revealed the irreversible electrochemical process that can be utilized to quantify the s...

beta-D-Xylosidase/alpha-L-arabinofuranosidase from Selenomonas ruminantium is the most active enzyme known for catalyzing hydrolysis of 1,4-beta-D-xylooligosaccharides to D-xylose. Catalysis and inhibitor binding by the GH43 beta-xylosidase are governed by the protonation states of catalytic base (D14, pKa 5.0) and catalytic acid (E186, pKa 7.2). Biphasic inhibition by triethanolamine of E186A ...

Catalysis and inhibitor binding by the GH43 beta-xylosidase are governed by the protonation states of catalytic base (D14, pK(a) 5.0) and catalytic acid (E186, pK(a) 7.2) which reside in subsite -1 of the two-subsite active site. Cationic aminoalcohols are shown to bind exclusively to subsite -1 of the catalytically-inactive, dianionic enzyme (D14(-)E186(-)). Enzyme (E) and aminoalcohols (A) fo...

New tris(2,2′-bipyridine)-type ruthenium(II) complexes with L-lysine-containing side chains form gels by hierarchical assembly of hydrogen bonded fibers in some organic solvents. These Ru(II) complex aggregates are more efficient photosensitizers for reduction of methyl viologen than Ru(bpy)3 in the presence of triethanolamine, a sacrificial electron donor. The increased rate of reduced viologe...

In order to control the deposition of Zn-related films by chemical bath deposition, effects Zn-complexing agent are analyzed. ZnS were produced technique employing sodium citrate, ethanolamine and Triethanolamine as complexing agents. The conditions for (ZnO) thin obtained through a thermodynamic analysis, using distribution diagrams molar fraction Zn complexes. From species Zn-ethanolamine, Zn...

STUDY OBJECTIVE Assessment of the tympanic membrane is often impeded by the presence of cerumen. We compared the ceruminolytic effects of triethanolamine polypeptide and docusate sodium in patients with cerumen. METHODS We conducted a prospective, randomized, controlled, double-blind trial on a convenience sample of cooperative adult and pediatric patients presenting to a university-based eme...

A Taguchi robust design method with an L₉ orthogonal array was implemented to optimize experimental conditions for the biosynthesis of triethanolamine (TEA)-based esterquat cationic surfactants using an enzymatic reaction method. The esterification reaction conversion% was considered as the response. Enzyme amount, reaction time, reaction temperature and molar ratio of substrates, [oleic acid: ...

Investigation of the electrochemical behavior using cyclic voltammetry and detection of [Mn(2+)(thiophenyl-2-carboxylic acid)2 (triethanolamine)] with adsorptive stripping differential pulse voltammetry. The electrochemical behavior of a manganese(II) complex [Mn(2+)(thiophenyl-2-carboxylic acid)2(triethanolamine)] (A) was investigated using cyclic and differential pulse voltammetry in an aceta...
