Product Description
Introduction:Cysteine, one of the 20 natural amino acids, is a non-essential amino acid containing sulfur (like methionine). Animals can be synthesized by methionine and serine. It can alleviate and repair radiation damage to human body. It also has a wide range of detoxification effects in human body, and is a therapeutic drug for acrylonitrile and aromatic acidosis. It helps to break away from alcohol addiction and is necessary for the brain and liver to function; it is necessary for the regeneration of liver cells

Function of Food Additive Grade Treatment of Hair and Skin Loss Amino Acid CAS 56-89-3 Bulk 99% L-Cystine Powder
L-cysteine is mainly used in medicine, 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 acrylonitrile 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). Cosmetics are mainly used in cosmetic water, perm, sunproof skin cream and so on.
