About The L-Lysine sulfate

1. Overview

L-Lysine sulfate is an important salt form of L-Lysine. It is rich in L-Lysine and has a wide range of applications in feed, food, medicine and other fields. It is a compound that plays a key role in the growth and development of organisms and the maintenance of normal physiological functions.

2. Physical and chemical properties

Appearance and properties: It usually appears as an off-white or light brown powder. This powder form is convenient for its operation in storage, transportation and various subsequent application scenarios (such as mixing with many raw materials in feed production, and compatibility with auxiliary materials in the pharmaceutical process, etc.), and is easy to accurately measure and evenly disperse.

Solubility: It has a certain solubility in water and can form a relatively stable solution. However, compared with some other lysine salts, its solubility may be slightly weaker, but it can still meet the needs of most practical application scenarios, such as the preparation of animal feed additives. The aqueous solution can be dissolved and used smoothly when it is used for spraying and adding. In organic solvents, L-Lysine sulfate has poor solubility, and its application mainly revolves around aqueous solution systems.

Stability: It is relatively stable under normal temperature, dry and suitable environmental conditions, but if it is exposed to adverse environmental factors such as high temperature, high humidity, strong light or strong oxidants, its chemical structure may change, resulting in reduced activity or even loss of efficacy. Therefore, appropriate protective measures need to be taken during storage and use, such as keeping it in a cool and dry environment and avoiding direct sunlight to maintain its stability.

3. Physiological function

Participate in protein synthesis: As an essential amino acid for humans and animals, L-lysine sulfate is a key component of protein in organisms. It follows specific genetic code information and cooperates with other amino acids in structures such as ribosomes in cells to form a variety of protein molecules with different functions in a certain order. These proteins play a vital role in almost all physiological processes of organisms, such as enzymes that catalyze biochemical reactions, actin and myosin that realize muscle contraction and relaxation, antibodies that participate in immune defense, etc., which are indispensable basic elements for maintaining normal life activities of the body.

Promoting growth and development: For organisms in the growth and development stage (especially children, adolescents and young animals, etc.), L-lysine sulfate is of great significance. It can help the healthy growth of bones, and by affecting the absorption and utilization of nutrients such as calcium, it provides better nutritional support for bone development, making bones more solid and strong; it also actively participates in the protein synthesis of muscle tissue, promotes muscle growth and development, and helps the body to continue to grow in physique and strength. It is one of the important nutrients to ensure normal growth and development.

Regulating immune function: It can affect the activity, proliferation and differentiation of immune cells (such as lymphocytes, etc.), enhance the overall immunity of the body, help organisms better identify and resist the invasion of external pathogens (such as bacteria, viruses, etc.), maintain the immune system in a good functional state, and play a certain auxiliary role in preventing diseases and recovering from diseases. For example, in the high-incidence season of infectious diseases, appropriate supplementation of preparations containing L-lysine sulfate can help improve the body’s resistance, reduce the risk of infection or alleviate symptoms after illness.

IV. Application fields

Feed industry:

It is a very commonly used amino acid additive in animal feed. Because animals (such as chickens and ducks in poultry, pigs and cattle in livestock) have limited ability to synthesize lysine and cannot meet their large demand for lysine during growth and development, L-lysine sulfate needs to be added to feed to supplement this nutritional gap, so as to promote animal growth, improve feed conversion rate, enable animals to more efficiently convert ingested feed into their own weight growth, enhance animal disease resistance, reduce the occurrence of diseases, and thus improve breeding efficiency.

Different animal species and different growth stages have different requirements for L-lysine sulfate. For example, young animals usually need relatively more L-lysine sulfate in the rapid growth stage. Therefore, when designing feed formula, the amount of addition should be accurately determined based on the specific animal species, age, feeding environment and other factors to achieve scientific and reasonable nutritional supplementation.

Food industry:

It can be used as a nutritional enhancer in some foods, especially those with plant protein as the main ingredient. By adding L-lysine sulfate, the amino acid composition of the food can be improved, making it closer to the ideal amino acid pattern required by the human body, thereby improving the overall nutritional value of the food and meeting the additional needs of different groups of people (such as vegetarians, the elderly, athletes, etc.) for amino acids. For example, adding L-lysine sulfate in some soy products and cereal products can further improve their nutritional value.

It can also be used for the research and development and production of special medical foods. For some patients with special health conditions such as abnormal amino acid metabolism or malnutrition, L-lysine sulfate and other nutrients can be reasonably added according to their physical needs to customize foods that meet their individual conditions, assist in disease treatment and improve health conditions.

Pharmaceutical industry:

In the medical field, L-lysine sulfate can be used as an auxiliary treatment for some diseases. For example, for children with growth retardation caused by malnutrition, an appropriate amount of L-lysine sulfate supplementation can help improve nutritional status and promote children’s normal growth and development. In addition, in the treatment of certain infectious diseases, given its role in regulating immune function, it can also assist in enhancing the body’s resistance and help patients recover better, but specific applications need to be carried out under the professional guidance of doctors. Doctors will comprehensively determine the medication plan based on the patient’s age, condition, physical condition and other factors.

V. Quality Standards and Testing

Quality Standards:

Different application fields have different emphasis on the quality requirements of L-lysine sulfate, but generally have strict restrictions on its content, impurity content and other aspects. In the field of feed additives, the content of its active ingredient L-lysine sulfate is required to meet the prescribed standard range, and there are corresponding upper limits for heavy metal impurities, moisture content, etc. to ensure that the product meets the requirements for safe and effective use and will not have adverse effects on animal health due to impurities and other problems.

In the field of medicine, its quality standards are more stringent. From the purity of raw materials to every link of the production process, the requirements of the Good Manufacturing Practice (GMP) must be strictly followed to ensure the quality stability and safety of the product, so that it can be reliably used in disease treatment and other aspects. In the field of food additives, it is also necessary to meet the corresponding food safety standards to ensure that the added food is harmless to the health of consumers.

Detection method:

The commonly used method for detecting the content of L-lysine sulfate includes high performance liquid chromatography (HPLC). After the sample is injected into the mobile phase, the distribution coefficient difference between the stationary phase and the mobile phase is used for separation. Then, the peak area and other related signals of L-lysine sulfate are detected by the detector, and compared with the standard to accurately determine its content.

For the detection of impurity content, such as heavy metal impurities, atomic absorption spectroscopy can be used. The content of heavy metals can be determined by detecting the absorption spectrum of specific metal elements in the sample. Through the comprehensive use of multiple detection methods, the quality of L-lysine sulfate products can be comprehensively evaluated to determine whether it meets the corresponding quality standards.

VI. Storage and transportation requirements

Storage conditions:

It should be stored in a cool, dry and well-ventilated environment. It is generally recommended that the storage temperature be below 30℃ and avoid direct sunlight, because high temperature and strong light can easily cause it to undergo chemical reactions such as decomposition and oxidation, affecting its quality and performance. At the same time, moisture-proof measures should be taken, and packaging containers with good sealing performance should be used to prevent it from absorbing moisture in the air and causing agglomeration and deterioration, so as to ensure its stability during storage.

It is also necessary to store it separately from oxidants, acids, alkalis and other substances that may react chemically to avoid accidents and ensure that the storage safety and product quality are not affected.

Transportation requirements:

During transportation, it is also necessary to avoid adverse environmental conditions such as high temperature, sun exposure, and rain. Choose appropriate packaging materials, such as packaging bags or packaging barrels with moisture-proof, light-proof, and sealed functions, to ensure that the packaging is intact and prevent external factors from damaging its internal chemical structure and quality. And it is necessary to arrange the transportation route and transportation tools reasonably to avoid bumps, collisions, and other situations that may cause packaging damage, and ensure that the product is transported safely and intact to the destination.

VII. Precautions for use

Dosage: Whether it is in feed addition, food fortification or medical application, the dosage needs to be strictly controlled. In the feed industry, the amount of addition should be scientifically and reasonably determined based on factors such as the type of animal, growth stage, and feeding environment. Excessive addition may cause digestive problems such as diarrhea in animals. In food applications, it should be added in accordance with the use limit specified in relevant food safety standards to avoid excessive addition that affects food quality and consumer health. In the medical field, the dosage must be determined strictly according to the doctor’s instructions. The doctor will comprehensively consider the patient’s age, condition, physical condition and other factors to accurately give the appropriate dosage to prevent adverse reactions caused by improper dosage.

Incompatibility: When adding L-lysine sulfate to feed, pay attention to its interaction with other feed additives. For example, when it exists with some minerals (such as calcium, iron, etc.), it may affect each other’s solubility or stability. Therefore, scientific formula design is needed to ensure that the overall feed is nutritionally balanced and the ingredients are compatible with each other. In medical applications, if other drugs are taken at the same time, drug interactions may occur. It is necessary to inform the doctor that L-lysine sulfate is being used so that reasonable medication adjustments and monitoring can be made.
