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

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

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

1.L-cistein  has effective detoxification.

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

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

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

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

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

7.L-cistein  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-cistein 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-cistein CAS:52-90-4 Application:

L-cistein 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-cistein has an effective detoxification.

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

3. L-cistein 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-cistein can improve the symptoms of inflammation and skin allergies.

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

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

7. Cistein je neke vrste naravna aminokislina, ki ima veliko uporab pri predelavi hrane, uporablja se predvsem za peko izdelkov, kot nujna sestavina za izboljšanje testa

8. Cistein je nekakšen reducent, lahko spodbuja tvorbo glutena, zmanjša čas, potreben za mešanje, in energijo, potrebno za zdravilo, cistein s spreminjanjem beljakovinskih molekul in beljakovinskih molekul med notranjo disulfidno vezjo, oslabi strukturo beljakovine, se ta beljakovina raztegne.
