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

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

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

1.L-Sistein  has effective detoxification.

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

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

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

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

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

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

L-Sistein 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-Sistein has an effective detoxification.

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

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

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

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

7.Sistein, bir tür doğal amino asittir, gıda işlemede birçok kullanıma sahiptir, esas olarak hamur geliştiricinin gerekli bir bileşeni olarak pişirme ürünleri için kullanılır.

8.Sistein bir tür indirgeyicidir, gluten oluşumunu teşvik edebilir, karıştırma için gereken süreyi ve tıbbi, sistein için gereken enerjiyi, iç disülfid bağı arasındaki protein moleküllerini ve protein moleküllerini değiştirerek azaltabilir, yapısını zayıflatabilir. protein, bu protein gerilir.
