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

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

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

1.L-cisztein  has effective detoxification.

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

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

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

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

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

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

L-cisztein 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-cisztein has an effective detoxification.

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

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

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

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

7. A cisztein egyfajta természetes aminosav, számos felhasználási lehetőséggel rendelkezik az élelmiszer-feldolgozásban, főleg sütőipari termékekhez használják, a tésztajavító szükséges komponenseként

8. A cisztein egyfajta reduktáns, elősegítheti a glutén képződését, csökkentheti a keveréshez szükséges időt és a gyógyszerek, a cisztein energiáját azáltal, hogy megváltoztatja a fehérje molekulákat és a fehérje molekulákat a belső diszulfid kötés között, gyengíti a fehérje, ez a fehérje megnyúlik.
