Lysin Hydrochlorid

Several essential amino acids have been shown to be the limiting factor of nutrition in plant proteins. In advanced countries, the ratio of vegetable proteins to animal proteins in foods is 1.4 1. In underdeveloped nations, the ratio is 3.5 1. which means that people in underdeveloped areas depend upon vegetable proteins. Among vegetable staple foods, wheat easily can be fortified. It is used as flour all over the world. L-Lysine hydrochloride (0,2% ) is added to the flour. Wheat bread fortified with lysine is used in several areas of the woilcl in Japan it is supplied as a school ration. 

Exercises in thin-layer chromatography. Separation of amino acids. Prepare solutions of DL-alanine, L-leucine and L-lysine hydrochloride by dissolving 5 mg of each separately in 0.33 ml of distilled water, measured with a graduated 1 ml pipette (leucine may require warming to effect solution). Mix one drop of each solution to provide a mixture of the three amino acids and dilute the remainder of each solution to 1 ml to give solutions of the respective amino acids. The latter will contain about 5 pg of each amino acid per pi. Apply approximately 0.5 pi of each of the solutions to a Silica Gel G plate and allow to dry in the air (i.e. until the spots are no longer visible). 

A typical three-compartment ED stack using bipolar, cationic, and anionic membranes (Figure 8A) was patented by Mani (2000) to produce lysine hydrochloride. By feeding the salt compartments with a salt (e.g., NaCl, KC1, or LiCl) solution, the base and acid ones with water and a lysine-rich solution, respectively, the salt can be split into an alkali and hydrochloric acid. The latter reacts with lysine, thus yielding the amino hydrochloride. 

To 18.3 g of L-lysine hydrochloride dissolved in 100 ml of water is added 10 ml of 37% aqueous solution of formaldehyde. To the resultant mixture is added 44.0 g of anhydrous tetracycline dissolved in 500 ml of tetrahydrofuran. After thorough mixing the product forms over a period of about 15 min as an oily layer which after separation from the aqueous phase is added dropwise to 3 L of stirred isopropyl alcohol. The product after recovery by filtration, is reslurried with acetone, filtered and dried at 65°C at reduced pressure.

The management of acute phencyclidine intoxication has been reviewed (29,30,31,32). Acidification of the urine enhances its renal clearance (33). All of the following have been used to achieve this ammonium chloride 1 g qds with sufficient water or cranberry juice lysine dihydrochloride 2 g tds with sufficient water or cranberry juice lysine hydrochloride 2 g qds with water or cranberry juice cranberry juice 18 or more oz/day alone or plus lysine, ammonium chloride, or ascorbic acid (34).

Authentic pyridoxyl-lysine has been prepared by Schnackerz and Noltmann (1971) by borohydride reduction of a mixture of poly-L-lysine hydrochloride (20 mg) and 0.38 moles of pyridoxal, which had been allowed to stand for 10 min at 0°C in 50 mM sodium phosphate (pH 6.0). Low molecular weight impurities were removed by dialysis against 50 mM sodium acetate buffer (pH 6.0). After dialysis the resulting product can be hydrolyzed in 6 N HCl to yield pyridoxyl-lysine and some lysine. The latter contaminant can be minimized by... 

Capromab pendetide is the murine MAb, 7E11-C5.3, conjugated to the linker-chelator, glycyl-tyrosyl-(A/-diethylenetriaminepentaacetic acid)-lysine hydrochloride (GYK-DTPA-HCI). Given with Indium In 111. 

Each gram of gel contains 100 pg of becaplermin, sodium carboxymethylcellulose, sodium chloride, sodium acetate trihydrate, glacial acetic acid, water for injection, and methylparaben, propylparaben, and m-cresol as preservatives, and L-lysine hydrochloride as a stabilizer. 

The above procedure for lysine hydrochloride is a modification of that published by Braim. ...
