L-Cysteine hydrochloride monohydrate

L-Cysteine HCl monohydrate is a non-animal origin product that can be used as a pharmaceutical preparation and is also used in the synthesis of human growth factor. L-Cysteine HCl monohydrate is an amino acid that reacts with sodium citrate to form a reaction solution. This reaction solution is used in the treatment of bone cancer and has been shown to have clinical properties. L-Cysteine HCl monohydrate binds to the neurokinin-1 receptor, inhibiting the release of substance P, which inhibits tumor cell proliferation by blocking the signal transduction pathway. The polymerase chain reaction (PCR) technique has been used to show that l-cysteine HCl monohydrate suppresses gene expression and protein synthesis in model systems. In addition, it has been shown that L-Cysteine HCl monohydrate inhibits the activity of surface methodology, such as calcium pantothenate and hydrochloric acid, which are important for protein synthesis

Stability Moisture Sensitive Applications L-Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. L-Cysteine is commonly used as a precursor in the food and pharmaceutical industries. L-Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours. References Hui, N. et al.: Meat Sci.

L-Cysteine is a nonessential amino acid that has the ability to disrupt bacterial cell membranes. It can be produced by hydrolysis of human hair, feathers, and animal hides. L-Cysteine is used as a food additive and flavouring agent in human food and animal feed. It is also used as an additive in the manufacture of plastics, adhesives, and rubber products. L-Cysteine hydrochloride monohydrate (L-Cys HCl) is a white crystalline powder that dissolves readily in water. L-Cys HCl has been shown to have anti-inflammatory properties due to its ability to inhibit the production of prostaglandins.

L-Cysteine hydrochloride monohydrate is used as a precursor in food, pharmaceutical and personal care products. It is actively involved in the production of flavors such as meat flavor obtained by reacting with sugars. It plays an important role as a key raw material for the manufacture of N-acetyl-L-cysteine, S-carboxymethyl-L-cysteine and L-cysteine base. It is involved in the treatment of liver disease as an antioxidant and antidote. Being an essential amino acid, it used as animal feed especially for sheep, which is responsible the growth of wool. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Due to its high reactivity towards formaldehyde, cysteine should be added as scavenger when cleaving His(Bom)-containing peptides, especially in case of an N-terminal Cys. CAS Number (net): 52-90-4.
