Uses

1. Food Industry:
   • Lysine is an important component of proteins and one of the eight essential amino acids that the human body cannot synthesize but needs. It is an excellent food enhancer.
   • Adding lysine to beverages, rice, flour, canned food, etc., can improve protein utilization, promote growth and development, increase appetite, reduce disease, and enhance physical fitness.
   • It has deodorizing and preservative effects in canned food.
2. Pharmaceutical Industry:
   • Can be used to prepare compound amino acid infusions, which have better effects and fewer side effects than hydrolyzed protein infusions.
   • Can be formulated with various vitamins and glucose into nutritional supplements that are easily absorbed by the stomach and intestines after oral administration.
   • Lysine can also improve the performance and efficacy of certain drugs.

Synthesis and Source

• Synthesis Method: L-Lysine is generally supplied in the market as L-Lysine hydrochloride, which is more stable than free L-Lysine. Free L-Lysine can be prepared from L-Lysine hydrochloride.
• Source: Can also be obtained by hydrolyzing animal proteins or synthesized from phenylacetyl piperidine.

Storage and Transportation

• Storage Conditions: Store in a dry, clean, and cool place below 0°C in a sealed container.
• Transportation: Handle with care, protect from moisture and sunlight, and do not mix with toxic and harmful substances.

Precautions

• Safety: L-Lysine, widely used in the food and pharmaceutical industries, is considered safe, but excessive intake or use in inappropriate situations may lead to adverse reactions.
• Drug Use: When L-Lysine hydrochloride granules are used as a medication, follow medical advice, pay attention to drug interactions, and be aware of adverse reactions.
