Raw material L-Lysine hydrochloride

L-Lysine hydrochloride More Info

L-Lysine hydrochloride is a hydrochloride salt form of L-lysine, an essential amino acid that cannot be synthesized by the human body and must be obtained through dietary intake or nutritional supplements.

Chemical Properties

Chemical Formula: C₆H₁₄N₂O₂·HCl

Molecular Weight: 182.65 g/mol

Physical Appearance: It typically exists as white or almost white crystalline powder, odorless or with a slight characteristic odor, and is highly soluble in water, sparingly soluble in ethanol.

Optical Activity: As an L-configured amino acid, it has optical rotation, with a specific rotation range usually between +20.3° and +21.5° under specified conditions (e.g., in water solution).

Main Functions and Applications

Nutritional Supplement FieldL-lysine is one of the limiting amino acids in cereal-based diets. L-lysine hydrochloride is widely added to foods such as baked goods, dairy products, and infant formula to balance amino acid composition, improve protein nutritional value, and meet the nutritional needs of humans and livestock. In animal feed, it is used to promote the growth and development of poultry and livestock, increase feed conversion rate.

Pharmaceutical FieldIt can be used as a raw material for amino acid infusion, which is applied in clinical settings to supplement amino acids for patients with malnutrition, post-operative recovery, or those with impaired digestive function. Additionally, it is involved in the synthesis of certain drugs, and some studies indicate that L-lysine may help enhance immune function and promote wound healing by participating in protein synthesis in the body.

Cosmetic FieldIt is added to skin care products as a functional ingredient. It can penetrate the stratum corneum to a certain extent, help maintain skin moisture, improve skin barrier function, and also has a certain effect on relieving skin dryness and roughness.

Safety and Regulatory Compliance

L-lysine hydrochloride is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). In the European Union, it is listed as a permitted food additive and feed additive. When used within the recommended dosage range, it has no obvious toxic side effects on the human body. However, excessive intake may cause gastrointestinal discomfort such as nausea and diarrhea.

Storage Requirements

It should be stored in a sealed, cool, dry place, away from direct sunlight and high temperature, to prevent moisture absorption and deterioration.
