L-Glutamine
Introduction L-glutamine is also known as glutenamide and L-glutamic acid-5-amide. White needle-shaped crystal or powder. The molecular weight is 146.15. Melting point 184～185℃. Soluble in water, insoluble in methanol, ethanol, ether, benzene, acetone, chloroform, ethyl acetate Chemicalbook. Stabilised in a neutral solution. It is easy to decompose into glutamic acid in acid or hot water, or to be esterified into pyrrole carboxylic acid. No smell. It has a slightly sweet fragrance. This... -
L-Valine
Introduction L-valine is a branched-chain amino acid , which cannot be synthesised by the animal body itself. It must be ingested from daily ration to meet its nutritional needs, so it is an essential amino acid. Amino acids are the basic structural units of protein synthesis, the predecessors of other amines needed for metabolism, and are indispensable substances for life. At present, there are 20 to 30 known amino acids, some of which can be synthesised in the human body and are called... -
L-Isoleucine
Chemical properties white crystalline or crystalline powder, odourless and slightly bitter. Mp284℃ (decomposition), 168-170℃ sublimation. The solubility in water is 4.12%, which is extremely difficult to dissolve in ethanol and ether. USE Amino acid drugs. It is a nutritional supplement, mixed with other carbohydrates, inorganic salts and vitamins for injection. It is used in amino acid infusions and preparations with other amino acids. -
L-Histidine
Introduction The product form of L-hertidine is a white powdery crystal. It is an important amino acid raw material. It is a semi-essential amino acid for the human body. It is mainly used as a raw material for amino acid infusion and oral amino acid Chemicalbook preparations. In addition, it is also an important drug for the treatment of heart disease, anaemia, rheumatoid arthritis, digestive tract ulcers and substantial hepatitis. In It is more and more widely used in the field of medi... -
Taurine
Introduction Taurine, also known as β-aminoacetyl sulphonic acid, was first isolated from bovine yellow, hence the name. The appearance is colourless or white oblique crystal, odourless, chemical book chemical properties are stable, soluble in ether and other organic solvents, a sulphur-containing non-protein amino acid, which exists in a free state in the body and does not participate in the biosynthesis of proteins in the body. Chemical properties White crystalline or crystalline ... -
Creatine
Introduction Creatine, also known as α-methylmethyl acetic acid, is a natural nutrient that exists in the human body. It can also be synthesised from arginine, glycine and methionine in the liver, kidney and pancreas: under the catalysis of renal arginine glycine trans-benzyme, the benzyl group of arginine is transferred to glycine. On the amino group, acetic acid is produced. Then the liver is catalysed by methyltransferase of acetic acid, and the methyl of S-adenosine methionine is tra...
