    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.

    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.
