L-cystéine CAS:52-90-4 Specification:

L-cystéine CAS:52-90-4 Introduction:

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

1.L-cystéine  has effective detoxification.

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

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

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

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

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

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

L-cystéine 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-cystéine has an effective detoxification.

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

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

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

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

7. La cystéine est une sorte d'acide aminé naturel, a de nombreuses utilisations dans la transformation des aliments, elle est principalement utilisée pour les produits de boulangerie, en tant que composant nécessaire de l'améliorant de la pâte

8. La cystéine est une sorte de réducteur, elle peut favoriser la formation de gluten, réduire le temps nécessaire au mélange et l'énergie requise pour les médicaments, la cystéine en modifiant les molécules de protéines et les molécules de protéines entre la liaison disulfure interne, affaiblir la structure du protéine, cette protéine est étirée.
