L-cisteină CAS:52-90-4 Specification:

L-cisteină CAS:52-90-4 Introduction:

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

1.L-cisteină  has effective detoxification.

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

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

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

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

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

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

L-cisteină 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-cisteină has an effective detoxification.

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

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

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

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

7. Cisteina este un fel de aminoacid natural, are multe utilizări în procesarea alimentelor, este utilizată în principal pentru produse de copt, ca o componentă necesară pentru ameliorarea aluatului

8. Cisteina este un fel de reductant, poate promova formarea glutenului, reduce timpul necesar amestecării și energia necesară medicamentului, cisteina prin schimbarea moleculelor de proteine ​​și a proteinelor dintre legătura disulfură internă, slăbește structura proteină, această proteină este întinsă.
