Factory Supply Best Price High Quality L-Histidine

Product Name: L-Histidine

Specifications: 99.30%

Appearance: White crystals or crystalline powder

CAS NO.: 71-00-1

Test Method: HPLC

Process: From pig blood and bovine blood. Pig blood was dried by spray drying, about 18kg per 100kg. L-histidine is commonly used as its hydrochloride salt ([7048-02-4]). The eluate containing L-histidine, concentrated to crystallization, while hot hydrochloric acid to pH of 2.5, immediately add 2 times the amount of ethanol, static, precipitation, filtration, namely L-histidine hydrochloride crude product, after decolorization, recrystallization, dry the finished product. L-histidine can also be extracted from the hydrolysis products of degreasing soybeans.

    Product Introduction

    Colorless needle or sheet crystallization, softened at 277℃ and resolved at 287℃. At 25℃, the solubility in water was 41.6g/L, extremely slightly soluble in alcohol and insoluble in ether and chloroform. Taste sweet. For human body, histidine can be by ordinary intermediate metabolites, so has been considered nonessential amino acids, but with the deepening of the study, people found that young animals and infants histidine synthesis cannot meet the needs of the body growth, even adult animals, if not added from food, synthesis in the body also can not meet the needs, so people also called half essential amino acids.
    Histidine is also one of the essential raw materials for the synthesis of some pharmaceutical intermediates.
    It is already known that the main metabolic pathways within organisms are deamination by histidine deaminase, formation of histamine by decarboxylases as well as amino transfer reactions. Biosynthesis is the formation of imidazole glycerol phosphate from the adenine portion of ATP and phosphate ribose filament phosphate for an amino-conversion reaction.
    L-histidine is a semi-essential amino acid, L-cystine, L-arginine, L-leucine, compound amino acid powder, cysteine is particularly important for the growth of infants and animals. Can be used as biochemical reagents and agents, and can also be used to treat heart disease, anemia, rheumatoid arthritis and other drugs. [1] Histidine is found in bananas, grapes, meat, livestock, milk, and dairy products. In addition, histidine is also found in green vegetables, but in low amounts.

    Product  Feature

    1. Improve growth performance
    The imidazole group of histidine is the main group for the ability of the buffer of proteins in tissues and plasma, and can activate the catalytic sites of many enzymes.The main metabolic pathways in organisms are deamination by histidine deaminase, formation of histamine by decarboxylase and amino transfer reactions. Biosynthesis is the formation of imidazole glycerol phosphate from the adenine portion of ATP and phosphate ribose filament phosphate for an amino group conversion reaction.

    2. Prevention of cataract effects
    L-histidine, an essential amino acid for the synthesis of cresine and sinosine, acts to prevent cataract in salmon by regulating internal osmolality.

    3. Enhance palatability
    Flavor agent, coheat with sugar amino monohydrogen group reaction, can produce substances with special aroma

    4. Safe and non-toxic
    Compound amino acid is one of the raw materials. For malnutrition, protein deficiency, severe gastrointestinal diseases, burns, and protein supplementation after surgery. There were no significant toxic or significant side effects.
