 Function  

1. For biochemical research.Preparation of biological medium.Used in biochemical and nutritional research, it has the function of promoting cell oxidation and reduction, increasing white blood cells and preventing the development of pathogenic bacteria.Mainly used for alopecia.Also used for dysentery, typhoid fever, influenza and other acute infectious diseases, asthma, neuralgia, eczema and a variety of poisoning disorders, and maintain the role of protein configuration.Also used as a food flavoring agent.

2. Biochemical reagent, used for the preparation of biological culture medium.It is also an important component of amino acid infusion and compound amino acid preparation.

3 as forage nutrition fortifier, conducive to animal development, increase weight and liver and kidney function, improve the quality of fur.

4. It can be used as cosmetics additive to promote wound healing, prevent skin allergy and treat eczema.

 Application Area 

1.Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acidcysteine. 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.

2.L- Cystine helps strengthen the immune system, reduce damage from free-radicals, repairRNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine. L-Cystine aids in preventing the side effects of chemotherapy and radiation. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow.

3.L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age spots.
