The Characteristics
and Uses：
|
1.
10%~15% used for food industry.
Lysine is one of significant compositions of protein. The body
requires Lys which is one of eight amino acids, but cannot
synthesize it must be provided in the diet. As tacking Lys in the
diet. As lacking Lys in the diet, therefore is called "the
first essential amino acid". For a good enhancing agent, to add
lysine into rice, flour, and can will rise up the rate for utilizing
protein so that it can enhance food nutrition greatly. It is also efficiencies
in improving growth, adjust appetite, reduce diseased and make body
stronger. it can deodorize and keep fresh in tinned food.
2. 5% used for pharmacy
Lysine is available for formatting complex amino acid perfusion and
making affection better than hydrolytic protein and less by-effection.
It can be made nutritional enhancing agent with various vitamins and
glucoses, and is easily absorbed by gastro intestine after oral.
Lysine can also better performances of some drugs and improve their
efficiency.
