Storage method
This product should be kept sealed, cool and dry.
Synthesis method
It can be extracted from the protein hydrolyzate produced by co-heating of protein and alkali or produced by organic synthesis using dihydropyran as raw material. The resulting product is DL-lysine. In fact, it is the same amount. A mixture of D-lysine molecules and L-lysine molecules are optical isomers of each other.
Purpose
Lysine is a key substance that helps other nutrients be fully absorbed and utilized by the human body. Only by supplementing enough L-lysine can the human body improve the absorption and utilization of food protein, achieve balanced nutrition, and promote growth and development.
