To investigate template effect on physicochemical properties of zeolite and enhance the molecular sieving properties, adsorption of methionine amino acid was studied by spectroscopic methods. Four zeolites such as methionine templated analcime, methionine templated zeolite P, N, N-dibenzyl N,N,N,N-tetramethylethylenediamine (DBTMED) templated analcime and free template analcime were synthesized...
In this study, the addition of organic methionine inhibitor (as an eco-friendly inhibitor) to 0.1 M sulfuric acid media on corrosion resistance of 316L austenitic stainless steel (fabricated by rolling method and three-dimensional (3D) printing method) was investigated. Open-circuit potential electrochemical test and impedance, and structural tests such as optical and electron microscopy and x-...
The Cover Feature shows a metal nanoparticle modified with the amino acid L-methionine and adsorption of enzyme acetylcholinesterase (AChE) on methionine-capped surface. Methionine-capped Ag Au nanoparticles (NPs) were tested as inhibitors AChE, they showed moderate inhibitory potential toward AChE. NPs are much larger than molecules cannot enter active site gorge, so inhibition occurs by block...
Using the amino acids methionine and serine reduced Schiff base and their copper(II) complexes were synthesized. The inhibition effect of these copper (II) complexes on the corrosion of mild steel in 1 M HCl solution was investigated. The corrosion inhibition action is studied through weight loss method. Among the tested complexes [CuCl(SMet)PPh 3 .H 2 O] exhibited better corrosion inhibition a...
The electrochemical oxidation behaviour at boron doped diamond and glassy carbon electrodes of the sulphur-containing amino acids cysteine and methionine, using cyclic and differential pulse voltammetry over a wide pH range, was compared. The oxidation reactions of these amino acids are irreversible, diffusion-controlled pH dependent processes, and occur in a complex cascade mechanism. The amin...
Absorption of L-methionine was measured in all parts of the human small intestine using transintestinal intubation and perfusion. In four normal subjects, adsorption was higher in the proximal than in the distal intestine. In two patients with nontropical sprue in relapse, there was a proximal zone of low absorption with higher absorption distally. In all parts of the small intestine, absorptio...
This study has the main purpose of testing natural carriers as more sustainable alternatives to polymeric coating. New clay-based hybrid organic–inorganic materials have been prepared. An innovative procedure for intercalation bioactive molecule is proposed. The synthesis process implies use mild operating conditions and does not require organic reactants or solvents. Moreover, carriers, milder...
