Production of l-Lysine From l-Lysine Monohydrochloride by Bipolar Membrane Electrodialysis

Desalination and Water Treatment, 2012
Abstract Bipolar membrane electrodialysis consisting of one bipolar membrane, one anion-exchange membrane and one cation-exchange membrane was performed to achieve the production of l-lysine from l-lysine (l-Lys) monohydrochloride. Several experimental parameters including the operation voltage, the initial l-Lys·HCl concentration and operation ...

Production of L-Lysine From L-Lysine Monohydrochloride by Electrodialysis

Desalination and Water Treatment, 2011
Production of L-lysine from L-lysine monohydrochloride was carried out by electrodialysis, using four-compartment electrodialysis apparatus with two cation-exchange membranes and one anion-exchange membrane. The process feasibility was tested with an effective membrane area of 25 cm2. Effects of L-Lys•HCl concentration, the molar ratio of L-Lys•HCl and

Influence of most reactive inorganic cation in the optical and biological activities of L-Lysine monohydrochloride crystal. [PDF]

Saudi J Biol Sci, 2020
Slow evaporation method was used to grow the pure and K+ ion doped L-Lysine monohydrochloride (L-LMHCL) crystals which has optical and antibiotic applications. The space group, structure and slight shifting of peaks are confirmed using single crystal XRD and the powder XRD. The FTIR analysis also shows that the K+ doped L-LMHCL has a slight shifting in

Reorientational dynamics of amino acids in aqueous solution probed by ultrafast optical Kerr effect spectroscopy [PDF]

Science and Technology of Advanced Materials
Reorientational relaxation of a solute in aqueous solution reflects the friction from its surroundings, yet observing solute-specific rotational motion at the microscopic level is difficult.

Effects of amino acids methionine, lysine, and taurine on feed intake and mRNA expression of appetite-related neuropeptides in layer-type chicks [PDF]

Poultry Science
Amino acids in the brain modulate eating behavior and energy balance. The aim of the present study was to investigate the effects of DL-methionine (DL-Met), l-lysine monohydrochloride (L-Lys-HCl), and taurine (Tau) on feed intake and the mRNA expression ...

A diatrizoic acid derivative for N-acylation of amino acids [PDF]

Results in Chemistry
3,5-Bis(acetamido)-2,4,6-triiodobenzoic acid, aka diatrizoic acid (DTZOH), is a major compound for the radiopaque material research. Iodine elements at the 2,4,6-positions are the origin of the radiopacity, but the bulkiness of iodine frequently inhibits

Isolable Cysteine Sulfenyl Iodide: Stabilization by a Molecular Cradle, Crystal Structure, and Biologically Relevant Reactivity. [PDF]

Chembiochem
An isolable cysteine sulfenyl iodide (Cys–SI) stabilized by a molecular cradle is reported. X‐ray analysis and reactivity studies reveal hydrolysis to sulfenic acid, electrophilic substitution with indoles, and high reactivity toward amines and dimedone, providing direct evidence for long‐standing proposals on iodine‐mediated protein modification ...
