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 növ təbii amin turşusudur, qida emalında çox istifadəyə malikdir, əsasən xəmir yaxşılaşdırıcı maddələrin zəruri komponenti kimi məhsullar bişirmək üçün istifadə olunur.

8. Sistein bir növ reduktandır, glütenin əmələ gəlməsini təşviq edə bilər, qarışıq üçün lazım olan vaxtı və dərman üçün lazım olan enerjini azaldar, daxili disülfid bağları arasındakı protein molekullarını və protein molekullarını dəyişdirərək sistein. protein, bu protein uzanır.
