Product Description

L-Cystine,is a covalently linked dimeric nonessential amino acid formed through the oxidation of cysteine. It is contained in many foods including eggs, meat, dairy products, and whole grains as well as in skin and hairs. L-cystine and L-methionine are the amino-acids required for wound healing and formation of epithelial tissue.

It is able to stimulate the hematopoietic system and promote the formation of white and red blood cells. It can also be used as a component of parental and enteral nutrition. It can also be used for the treatment of dermatitis and protection of liver function. L-cystine is manufactured through the enzymatic conversion from DL-amino thiazoline carboxylic acid. 

 

L-cysteine is mainly used in , cosmetics, biochemical research and so on. It is used in bread materials to promote the formation of gluten, promote fermentation, mold production and prevent aging. It is used in natural juice to prevent oxidation of vitamin C and browning of juice. The product has detoxification effect and can be used for poisoning and aromatic acidosis. It also has the function of preventing radiation damage to human body, and is also a medicine for treating bronchitis, especially as a phlegm-resolving drug (mostly in the form of acetyl L-cysteine methyl esterate).
