storage method
this product should be stored in a sealed, cool, dry place.
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.
