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

H&Z® L-Cysteine 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-Cysteine 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-Cysteine CAS:52-90-4 Function:

1.L-Cysteine  has effective detoxification.

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

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

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

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

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

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

H&Z® L-Cysteine 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-Cysteine has an effective detoxification.

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

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

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

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

7.Cysteine 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.Cysteine is a kind of reductant, it can promote the formation of gluten, reduce the time needed for mixing and the energy required for medicinal, cysteine by changing the protein molecules and protein molecules between the internal disulfide bond, weaken the structure of the protein, this protein is stretched.
