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

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

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

1.L-cisteina  has effective detoxification.

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

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

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

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

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

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

L-cisteina 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-cisteina has an effective detoxification.

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

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

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

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

7. La cisteina è una sorta di amminoacido naturale, ha molti usi nella lavorazione degli alimenti, viene utilizzata principalmente per prodotti da forno, come componente necessario dell'ammendante

8. La cisteina è una sorta di riducente, può promuovere la formazione di glutine, ridurre il tempo necessario per la miscelazione e l'energia necessaria per il medicinale, la cisteina modificando le molecole proteiche e le molecole proteiche tra il legame disolfuro interno, indebolire la struttura del proteina, questa proteina è allungata.
