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

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

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

1.L-cystein  has effective detoxification.

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

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

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

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

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

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

L-cystein 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-cystein has an effective detoxification.

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

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

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

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

7. cystein er en slags naturlig aminosyre, har mange anvendelser i fødevareforarbejdning, det bruges hovedsageligt til bagning af produkter som en nødvendig komponent af dejforbedringsmiddel

8. cystein er en slags reduktionsmiddel, det kan fremme dannelsen af ​​gluten, reducere den nødvendige tid til blanding og den krævede energi til medicin, cystein ved at ændre proteinmolekylerne og proteinmolekylerne mellem den interne disulfidbinding, svække strukturen i protein, dette protein strækkes.
