The production methods of this chemical are as follows: (1) Free L-Lysine could be obtained from L-lysine hydrochloride. (2) Firstly prepare raw material of Red blood cells, and then suspend it in sulfuric acid solution; Secondly, use the calcium hydroxide to precipitate, and then go through the washing, crystallization to get L-Lysine (CAS NO.56-87-1). (3) Synthesis method: caprolactam and furfural as the raw material.

As to its usage, it is widely applied in many ways. It could be used as the nutrition enhancer which could enhance the lysine in intensified [enriched] food; It could also used in biochemistry to cure the symptom of malnutrition, inappetence and hypoplasia; And it could be as the Aminoacetic Acid, and the feed additives.
