Product Details
Industrial grade L-Lysine owns a minimum purity of 99%, presenting as odorless white crystal powder. The substance decomposes at 215℃ melting point, and its boiling point will change along with decomposition reaction. It has extremely low vapor pressure under 25℃ environment and 1.24 relative density at 20℃. This raw maleic-anhydride.html">material features excellent water solubility, slightly soluble in ethanol, and completely insoluble in ether and benzene solvents. It maintains stable physical and chemical properties under conventional storage conditions, yet it cannot coexist with strong oxidants and heavy metal salts for long term placement.

Product Application of L-LysineCAS56-87-1
L-Lysine is an indispensable essential amino acid for human body metabolism and daily nutrition intake. It can effectively boost calcium absorption efficiency, promote muscle protein synthesis and accelerate tissue repair after surgery or sports injury. This substance is widely used in auxiliary improvement of herpes symptoms and oral cold sore problems. Its derivative lysine acetylsalicylate can be used for pain relief and auxiliary detox treatment. It is also a crucial functional additive in livestock and poultry feed industry. Moreover, this natural amino acid widely exists in daily foods such as red meat, fish and dairy products.
