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

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

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

1.L-cisteinas  has effective detoxification.

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

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

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

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

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

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

L-cisteinas 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-cisteinas has an effective detoxification.

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

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

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

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

7. Cisteinas yra natūrali aminorūgštis, daug naudojama maisto perdirbimui, daugiausia naudojama kepiniams, kaip būtinas tešlos pagerinimo komponentas

8. Cisteinas yra tam tikras reduktorius, jis gali skatinti glitimo susidarymą, sutrumpinti maišymui reikalingą laiką ir vaistams reikalingą energiją, pakeisdamas baltymų molekules ir baltymų molekules tarp vidinio disulfidinio ryšio, susilpninti struktūrą. baltymų, šis baltymas yra ištemptas.
