L-cisteína CAS:52-90-4 Specification:

L-cisteína CAS:52-90-4 Introduction:

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

1.L-cisteína  has effective detoxification.

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

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

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

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

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

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

L-cisteína 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-cisteína has an effective detoxification.

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

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

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

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

7.La cisteína es un tipo de aminoácido natural, tiene muchos usos en el procesamiento de alimentos, se utiliza principalmente para productos de horneado, como componente necesario para mejorar la masa.

8.La cisteína es un tipo de reductor, puede promover la formación de gluten, reducir el tiempo necesario para mezclar y la energía requerida para la cisteína medicinal al cambiar las moléculas de proteína y las moléculas de proteína entre el enlace disulfuro interno, debilitar la estructura del proteína, esta proteína se estira.
