Viadd Chemical Company is one reliable L-Cystine exporter from China!
L-Cystine is a non-essential amino acid. This means your body can synthesize sufficient L-cystine to meet its requirements.It is one of the important products the amino acid series. It is widely used in medical, chemical and food industries. Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine. It can be converted to cysteine by reduction and was discovered in 1810 but was not recognized as a component of proteins until 1899, when it was isolated from animal horn – it is particularly abundant in skeletal and connective tissues, hair and digestive enzymes.Viadd Chemical Company is one reliable L-Cystine exporter from China!

【Main Functions】
1. Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine.
2. It can be converted to cysteine by reduction and was discovered in 1810 but was not recognized as a component of proteins until 1899, when it was isolated from animal horn – it is particularly abundant in skeletal and connective tissues, hair and digestive enzymes.
3. L- Cystine that Viadd Chemical company supplied helps strengthen the immune system, reduce damage from free-radicals, repair RNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine.
4. L-Cystine aids in preventing the side effects of chemotherapy and radiation.
5. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow.
6. L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age sports.
【Applications】
1. As a necessary nutrients metabolism, Viadd Chemical Supplied L-Cystine can be used in biochemistry and nutrition research, and has the function of promoting cell oxidation and reduction of the body in pharm, increase the white blood cells and preventing the development of pathogenic bacteria and so on. Mainly used for all kinds of hair loss. It is also used in acute infectious diseases, such as dysentery, typhoid fever, influenza, asthma, neuralgia, eczema, and various kinds of toxic diseases, etc., and has the function of maintaining the structure of protein. Also used as a food flavoring agent.
2. It is a biochemical reagent, used for biological media preparation. It is a important part of amino acid infusion and compound amino acid. Viadd chemical company supplied L-cystine can be used in making derivatives such as L-cysteine, carboxymethyl cysteine, acetyl cysteine, cysteine series, production of raw materials.
3. It can be made into cosmetic additives, which can promote wound healing and prevent skin allergy and treatment effect such as eczema.
4. Be feed nutrition enhancer, be helpful for animal growth, increase the weight and liver and kidney function, improve the quality of fur.
5. Dosage :200-400mg per day (usually in 2-3 doses throughout the day).
