L-Zisteina CAS:52-90-4 Introduction:
L-Zisteina 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-Zisteina 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-Zisteina CAS:52-90-4 Function:
1.L-Zisteina has effective detoxification.
2.L-Zisteina can effectively prevent and treat radiation injury.
3.L-Zisteina can remove the skin melanin itself, change the nature of the skin itself.
4.L-Zisteina can improve the symptoms of inflammation and skin allergies.
5.L-Zisteina on horny skin disease is also effective hypertrophy.
6.L-Zisteina has a function to prevent biological aging.
7.L-Zisteina 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-Zisteina 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-Zisteina CAS:52-90-4 Application:
L-Zisteina 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-Zisteina has an effective detoxification.
2. L-Zisteina can effectively prevent and treat radiation injury.
3. L-Zisteina 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-Zisteina can improve the symptoms of inflammation and skin allergies.
5.L-Zisteina on horny skin disease is also effective hypertrophy.
6. L-Zisteina has a function to prevent biological aging.
7. Zisteina aminoazido natural moduko bat da, elikagaiak prozesatzeko erabilpen ugari ditu, batez ere labeko produktuetarako erabiltzen da, orea hobetzeko beharrezko osagai gisa.
8. Zisteina erredukzio mota bat da, glutenaren eraketa susta dezake, nahasketarako behar den denbora eta sendagaiak behar duen energia murriztu, zisteina barne disulfuro loturaren arteko proteina molekulak eta proteina molekulak aldatuz, eta egitura ahultzen du. proteina, proteina hori luzatu egiten da.
