L-(+)-Lysine (H-Lys-OH; Abbreviated Lys or K) (CAS: 63-91-2) is mainly used as feed additives, food fortifiers and pharmaticals. Lysine is one of the essential amino acids of human beings and mammals, which cannot be synthesized by the body itself and must be supplemented from food. Lysine has positive nutritional significance in promoting human growth and development, enhancing body immunity, antiviral, promoting fat oxidation, relieving anxiety and other aspects, but also can promote the absorption of some nutrients, can work synergistically with some nutrients, and better play the physiological functions of various nutrients. Since 1970, lysine has been commonly added to animal feed. The demand for L-lysine is also increasing in some applications, such as peptide synthesis chemistry, biochemical research, and preparation of lysine derivatives.
It is used in pharmaceutical industry. Lysine can be used to prepare complex amino acid infusion, which is better than hydrolyzed protein infusion and has fewer side effects. Lysine can be mixed with various vitamins, made into nutritional supplements, easy to be absorbed by gastrointestinal after oral. Lysine can also improve the performance of some drugs, improve the efficacy of drugs.
Used in food industry. Lysine is one of the important components of protein. It is one of the eight amino acids which can not be synthesized by human body itself but is very needed. It is an excellent food fortifying agent
Lysine is an essential amino acid, especially compatible with feed-grade L-threonine. And L-Lysine HCL is one of the most widely used amino acid.When added to animal feed, it can greatly increase feed potency and provide animals with more comprehensive nutrition. The addition of Lysine to the feed can adjust the balance of amino acids in the feed, promote the growth of livestock and poultry, improve meat quality, increase the utilization of feed nitrogen and reduce feed production costs. Lysine HCL is widely used to add piglet feed, breeding pig feed, broiler feed and prawn feed.
