Supply Cysteine Raw Materials powder L-Cysteine
Product Overview:
L-cysteine, also known as cysteine, is a non-essential amino acid. Amino acids are the building blocks of proteins, and proteins are the material basis of life, from humans to microorganisms, and none of them are made up of proteins. Proteins are composed of peptides, and the peptide chain of peptides is composed of amino acids. Different proteins are made up of peptide chains with different sequences and lengths of amino acids.Genes, which are genetically related, are actually chains of amino acids in different orders.

Cysteine Usage and Synthesis.
L-cysteine is mainly used in cosmetics, medicine and food.
In cosmetics, it is used in the preparation of perm essence, sunscreen, hair perfume and hair care essence.
In the pharmaceutical field, it is used to prepare methyl cysteine, ethyl cysteine, acetyl cysteine, methyl cysteine, ethyl cysteine and comprehensive amino acid preparations and other drugs.
Cysteine can be used as a protective drug against radiation damage. In food, L-cysteine is used as a bread fermentation aid (ripening agent), milk powder and juice with antioxidant stabiliser and pet animal food nutrients.
Uses of Cysteine.
L-Cysteine is mainly used in medicine, cosmetics and biochemical research. It is used in bakery materials to promote the formation of gluten and to promote fermentation, moulding and prevent aging.
It is used in natural fruit juice to prevent the oxidation of vitamin C and prevent the juice from turning brown.The product has a detoxification effect, can be used for acrylonitrile poisoning,
aromatic acid poisoning. The product has a detoxification effect, can be used for acrylonitrile poisoning, aromatic acid poisoning.
The product also has the effect of preventing radiation damage to the human body, and is also a drug for the treatment of bronchitis, especially as a phlegm remover (mostly in the form of acetyl L-cysteine methyl ester acid salt. In cosmetics, it is mainly used in beauty water, perm solution, and skin care creams for sun protection.
Synthesis of Cysteine.
Product method of Bulk Cysteine Powder.
1. tin particles reduction method will be dissolved in dilute hydrochloric acid cystine, filtration, filtrate add tin particles temperature reflux 2h. will be reduced to dilute the solution with water, remove the remaining tin particles, saturated with hydrogen sulfide, filtration, filter residue with a small amount of water, wash, filtrate, combined, concentrated under reduced pressure, cooling crystallisation, filtration, drying to L-cysteine hydrochloride.
2. Electrolysis reduction method will be distilled water, hydrochloric acid, cystine into the electrolysis tank stirring dissolved, maintained at 50 ℃ below the electrolysis to the end point. The electrolyte will be passed hydrogen sulfide for a few hours, filtration. Filtrate plus activated carbon decolourisation, filtration, concentration under reduced pressure, cooling crystallisation, filtration, drying, L-cysteine hydrochloride.
