L-cysteina CAS:52-90-4 Specification:

L-cysteina CAS:52-90-4 Introduction:

L-cysteina is a common amino acid in the body. It is one of the sulfur-containingα-amino acids. It is purple when exposed to nitroprusside (developed due to SH). It is present in many proteins and glutathione, and can form insoluble with Ag +, Hg +, Cu + and other metal ions Mercaptide. That is, R-S-M′, R-S-M″-S-R (M′, M″are each monovalent and divalent metals). Molecular formula C3H7NO2S, molecular weight 121.16. Colorless crystals. Soluble in water, ethanol, acetic acid and ammonia [1]

L-cysteina has many uses in food processing. It is mainly used in baked products as an essential ingredient for dough improvers. L-cysteine is a reducing agent, it can promote the formation of gluten, reduce the time required for mixing and the energy required for medicinal purposes. Disulfide bonds weaken the structure of the protein, so the protein stretches out

L-cysteina CAS:52-90-4 Function:

1.L-cysteina  has effective detoxification.

2.L-cysteina can effectively prevent and treat radiation injury.

3.L-cysteina can remove the skin melanin itself, change the nature of the skin itself.

4.L-cysteina can improve the symptoms of inflammation and skin allergies.

5.L-cysteina on horny skin disease is also effective hypertrophy.

6.L-cysteina has a function to prevent biological aging.

7.L-cysteina  is a kind of natural amino acid, has many uses in food processing, it is mainly used for baking products, as a necessary component of dough improver

8.L-cysteina is a kind of reductant, it can promote the formation of gluten, reduce the time needed for mixing and the energy required for medicinal.

L-cysteina CAS:52-90-4 Application:

L-cysteina is widely used in fields of medicine, food processing, biological study, materials of chemical industry and so on. It’s used as raw materials for manufacturing N-Acetyl-L Cysteine, S-Carboxymethyl-L Cysteine, and L Cysteine base, etc. Used in the cure of liver disease, antioxidant and antidote are a promotor for bread fermentation. It promotes the form of glutelin and prevents from getting aging. Also used in cosmetic.

1.L-cysteina has an effective detoxification.

2. L-cysteina can effectively prevent and treat radiation injury.

3. L-cysteina can remove the skin melanin itself, change the nature of the skin itself, the skin becomes natural whitening. It is a kind of ideal natural whitening cosmetics.

4.L-cysteina can improve the symptoms of inflammation and skin allergies.

5.L-cysteina on horny skin disease is also effective hypertrophy.

6. L-cysteina has a function to prevent biological aging.

7. Cysteina jest rodzajem naturalnego aminokwasu, ma wiele zastosowań w przetwórstwie spożywczym, jest używana głównie do produktów piekarniczych, jako niezbędny składnik polepszacza ciasta

8. Cysteina jest rodzajem środka redukującego, może promować tworzenie glutenu, skrócić czas potrzebny do mieszania i energię wymaganą do leczenia, cysteiny poprzez zmianę cząsteczek białka i cząsteczek białka między wewnętrznym wiązaniem dwusiarczkowym, osłabić strukturę białko, to białko jest rozciągnięte.
