L-Amino Acid

L-Cysteine hydrochloride anhydrous is a conditionally essential amino acid and a precursor to bioactive molecules such as hydrogen sulfide (H2S), glutathione and taurine. L-Cysteine hydrochloride inhibits ghrelin and reduces appetite in rodents and humans. L-Cysteine Hydrochloride Anhydrous usually appears as colorless to white crystals or crystalline powder with a slight sour taste. It has a higher melting point, good solubility in water, and the aqueous solution is acidic. In addition, it is soluble in alcohol, ammonia and acetic acid, but insoluble in organic solvents such as ether, acetone, and benzene.

L-cysteine hydrochloride monohydrate is a chemical substance that has detoxifying effects on acrylonitrile and aromatic poisoning, prevents radiation damage, treats bronchitis and resolves phlegm, and absorbs alcohol. It has a detoxifying effect on acetaldehyde in the body.

L-cysteine is an isomer of cysteine. L-cysteine base is an alkaloid. L-cysteine base is mostly used in medicine and is also an additive. Cysteine is white crystal or crystalline powder, soluble in water, slightly odorous, insoluble in ethanol, and insoluble in organic solvents such as ether. Melting point 240℃, monoclinic crystal system. Cysteine is one of the sulfur-containing amino acids and is a non-essential amino acid. In the body, the sulfur atom of methionine is replaced with the hydroxyl oxygen atom of serine, and is synthesized through cystathionine. Starting from cysteine, glutathione can be generated. glycopeptide. Cysteine is stable to acid, but is easily oxidized to cystine in neutral and alkaline solutions.

L-Theanine is naturally found in green tea. It can also be obtained by heating L-glutamic acid under high pressure to make pyrrolidone carboxylic acid, adding anhydrous monoethylamine and heating under high pressure. Theanine (L-Theanine) is a unique free amino acid in tea. L-Theanine is glutamic acid γ-ethylamide, which has a sweet taste. Theanine content varies depending on the variety and part of tea. Theanine accounts for 1%-2% by weight in dry tea.

L-isoleucine is an essential amino acid that is vital to human and animal health. It is widely used in the fields of medicine, food, health care, feed, chemical industry and agriculture.

L-Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA. It is ubiquitous in higher plants. It is also the precursor of 5-hydroxytryptamine, an important neurotransmitter in the human body. It can be used during pregnancy. Nutritional supplement for women and special milk powder for infants and young children. It is used for niacin deficiency (pellagra). As a tranquilizer, it can regulate mental rhythm and improve sleep. It is also one of the raw materials of compound amino acid infusion.

Tyrosine (L-tyrosine, Tyr) is an important nutritional essential amino acid that plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, pharmaceutical and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as peptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as tanshinol, resveratrol, and hydroxytyrosol are discovered in vivo, L-tyrosine is increasingly developing into a platform compound.

L-proline (proline for short) is one of the twenty amino acids used for protein synthesis in the human body. It is colorless to white crystals or crystalline powder at room temperature. It has a slight odor and a slightly sweet taste. It is easily soluble in water and ethanol. Insoluble in ether, butanol and isopropyl alcohol, soluble in inorganic acids. Amino acids are the general name for a class of organic compounds containing amino and carboxyl groups. The presence of amino acids in the human body not only provides important raw materials for protein synthesis, but also provides a material basis for promoting growth, normal metabolism, and maintaining life.

L-arginine is an organic compound with the molecular formula C6H14N4O2. It is a non-essential amino acid for adults, but its production rate in the body is slow. It is an essential amino acid for infants and young children and has a certain detoxification effect. It is found in large amounts in protamine, etc. It is also the basic component of various proteins and is widely present.

L-Glutamine is an important amino acid widely used in medicine, food, health products and other fields.

L-Threonine (L-Serine) is an amino acid and one of the important components in living organisms. White crystalline powder, sweet and astringent in taste, soluble in water. It plays an important metabolic and regulatory role in organisms and is one of the components of protein.

Glycine hydrochloride is a salt compound formed by glycine and hydrochloric acid, usually in the form of a white crystalline solid. This compound has important uses in industry and medicine and is often used as pharmaceutical raw materials or other industrial processing purposes.
