Л-цистеин CAS:52-90-4 Specification:

Л-цистеин CAS:52-90-4 Introduction:

Л-цистеин 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]

Л-цистеин 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

Л-цистеин CAS:52-90-4 Function:

1.Л-цистеин  has effective detoxification.

2.Л-цистеин can effectively prevent and treat radiation injury.

3.Л-цистеин can remove the skin melanin itself, change the nature of the skin itself.

4.Л-цистеин can improve the symptoms of inflammation and skin allergies.

5.Л-цистеин on horny skin disease is also effective hypertrophy.

6.Л-цистеин has a function to prevent biological aging.

7.Л-цистеин  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.Л-цистеин is a kind of reductant, it can promote the formation of gluten, reduce the time needed for mixing and the energy required for medicinal.

Л-цистеин CAS:52-90-4 Application:

Л-цистеин 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.Л-цистеин has an effective detoxification.

2. Л-цистеин can effectively prevent and treat radiation injury.

3. Л-цистеин 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.Л-цистеин can improve the symptoms of inflammation and skin allergies.

5.Л-цистеин on horny skin disease is also effective hypertrophy.

6. Л-цистеин has a function to prevent biological aging.

7. Цистеин е еден вид природна аминокиселина, има многу намени во преработката на храна, главно се користи за печење производи, како неопходна компонента на подобрувачот на тестото

8. Цистеин е еден вид редуктант, може да промовира формирање на глутен, да го намали времето потребно за мешање и енергијата потребна за лековити, цистеин со промена на молекулите на протеините и молекулите на протеините помеѓу внатрешната врска со дисулфид, ја ослабуваат структурата на протеини, овој протеин се протега.
