L-Histidine Monohydrochloride

On the other hand, L-alanine, glycine and L-threonine taste mainly sweet [26]. Only for these amino acids, the potentials of channels 1 and 2 decreased. L-Glutamic acid and L-histidine monohydrochloride, which taste mainly sour, increased each of the potentials of channels 1-5 to almost the same degree. Only monosodium L-aspartate elicits mainly umami taste in humans among amino acids used here the response pattern was different from those of the other amino acids. 

Maillard reaction products were obtained by refluxing 100 ml of distilled water containing 0.1 mol L-histidine monohydrochloride mono-hydrate and 0.05 mol D-glucose for 20 h. The pH of the reaction mixture was adjusted to 7.0 with potassium hydroxide before starting the reaction. 

We use 5 mM L-histidine monohydrochloride (pH 7.0) as a homogenization buffer. For plant tissues containing secondary metabolites that can inhibit enzyme activity (e.g., resins, phenolics, tannins), complex extraction buffers are usually required.11 14,17 Examples of extraction buffers for... 

L-Histidine Monohydrochloride occurs as white crystals or as a crystalline powder. It is soluble in water, and insoluble in alcohol and in ether. It melts with decomposition at about 250° (after drying). 

Fig. 9.10 ID C spectrum of L-histidine monohydrochloride monohydrate recorded using the SS-APT method. Resonances due to carbons with an even (i.e., quaternary and CHj moieties) or odd (i.e., CH and CH3 moieties) number of attached protons are positive or...

Figlu, formiminoglutamic acid IpyA, imidazolepyruvic acid UroA, urocanic acid. L-histidine monohydrochloride is dissolved in water and given orally after an overnight fast. 350 mg of urocanic acid in a 1 mM solution of NaOH at pH 7.0 was injected slowly i.v. after an overnight fast. The plasma and urine samples should be frozen immediately after collection in order to prevent the decomposition of histidine metabolites. 

Eor colorfastness to perspiration, ISO 10S-E04, the specimen is immersed in a solution of 0.5 g/L of 1-histidine monohydrochloride monohydrate and 5 g/L sodium chloride buffered to either pH 8.0 (alkaH perspiration test) or pH 5.5 (acid perspiration test) in a dish at 50 1 Hquor-to-goods ratio, at room temperature for 30 min. The specimen is removed and, as in the water test EOl, left for 4 h between plates at 37°C before drying and assessing both test piece and adjacents. 

Hydroxy-L-lysine monohydrochloride [32685-69-1 ] M 198.7, [oi]q +17.8° (6M HCl), pKj 8.85, pK 9.83. Likely impurities are 5-a//o-hydroxy-(D and L)-lysine, histidine, lysine, ornithine. Crystd from water by adding 2-9 volumes of EtOH stepwise.
