What is L-Lysine acetate USP?
Xi'an Faithful BioTech Co., Ltd. is situated in Xi'an, the birthplace of the ancient Silk Road. Leveraging the city's mature logistics network and abundant fine chemical industrial resources, our enterprise has grown into an integrated fine chemical provider that delivers products to global partners. L-Lysine acetate USP, CAS No. 57282-49-2, is an organic salt compound formed by the combination of the essential amino acid L-lysine and acetic acid. Its molecular formula is C₈H₁₈N₂O₄, and its molecular weight is 206.24. It exhibits overall stable physicochemical properties, appearing as a uniform white crystalline powder. It has excellent water solubility, being fully soluble in pure water and slightly soluble in alcohols. Its aqueous solution has a mild pH range, and its quality can be maintained long-term by storing it in a cool, dry environment. L-Lysine acetate is one of the essential amino acids for the human body. It not only participates in certain metabolic processes but also affects the metabolism and absorption of other amino acids. Current research indicates that lysine can inhibit the replication of herpes simplex virus, has a preventive effect on angina pectoris and myocardial infarction, and improves memory function in patients with memory loss.
Application of L-Lysine acetate USP
L-Lysine acetate USP has applications spanning multiple fields, including biological research, food processing, animal husbandry, and fine synthesis. In biological laboratories, it serves as a core nitrogen source for cell culture and biological model experiments, providing basic amino acid substrates for cell growth and peptide synthesis reactions. It is also a commonly used matrix for various biochemical standard samples. In the food processing industry, lysine is a scarce limiting amino acid in cereal raw materials. Adding L-Lysine acetate to baked cereals, meal replacement products, and infant nutritional supplements can fill the amino acid gaps in ingredients, improve overall protein utilization, and also serve as a nitrogen source in fermentation processes, regulating the acid-base environment of the system and optimizing microbial fermentation efficiency. In animal husbandry, it is often added to compound feeds for young poultry and livestock to aid in protein synthesis and optimize growth. In the fine chemical synthesis field, relying on the amphoteric structure of amino and carboxyl groups within the molecule, it can participate in various organic synthesis reactions and is used in the research and development of trace element sustained-release formulations.

Mechanism of action of L-Lysine acetate
Supplementing Limiting Amino Acids and Optimizing Protein Synthesis Efficiency
Lysine is an essential amino acid that humans, animals, and plants cannot produce on their own, and its content is relatively low in grains and whole grains. L-Lysine acetate has good water solubility and mild properties. After dissociation, it releases free L-lysine, which serves as a basic building block for peptide and protein synthesis, participating in the formation of various functional and structural proteins in the body, improving overall protein absorption and utilization, and compensating for the deficiencies in the amino acid ratio of natural foods.
Regulating the Acid-Base Balance and Stabilizing the Complex System Environment
The molecule is formed by the neutralization of lysine and acetic acid to form a salt, resulting in an aqueous solution with a near-neutral pH and no strong acid radical residue. When added to complex formulations and microbial culture systems, it can buffer pH fluctuations, preventing the environment from becoming too alkaline due to a single basic amino acid, maintaining a stable and mild reaction environment, and ensuring the normal metabolic activities of microorganisms and cells.
Supporting microbial proliferation and enhancing fermentation activity
The dissociated free lysine can serve as a dedicated organic nitrogen source for microorganisms, supplying the nitrogen element required for the growth and reproduction of the microbial community, promoting the synthesis of enzymes in the microorganisms, and accelerating the fermentation metabolic rate; at the same time, the mild pH will not inhibit the activity of the strain, making it suitable for various food fermentation and biological cultivation processes.
