The product we are introducing is Factory Supply L-lysine monohydrate with the CAS number 39665-12-8. L-lysine monohydrate is an essential amino acid that cannot be synthesized by the human body and must be obtained through diet or supplements. It appears as a white crystalline powder with good solubility in water.
Some key parameters include its high purity level, which ensures its effectiveness in various applications. The molecular formula of L-lysine monohydrate is C₆H₁₄N₂O₂·H₂O, and its molecular weight is approximately 182.20 g/mol. It has a specific rotation and melting point within a defined range, which are important quality indicators.
In the field of nutrition, L-lysine monohydrate is widely used as a dietary supplement. It plays a crucial role in protein synthesis, which is essential for growth, repair, and maintenance of body tissues. For children and adolescents, it can contribute to healthy bone development and growth spurts. In adults, it helps maintain muscle mass and supports the immune system.
In the animal feed industry, it is an important additive. Animals, especially poultry and swine, have a high requirement for lysine. Adding L-lysine monohydrate to animal feed can improve the quality of the feed, enhance the growth performance of animals, and increase the efficiency of feed conversion. This leads to better animal health and higher-quality animal products.
It also has applications in the pharmaceutical industry. It can be used in the formulation of drugs for treating certain diseases related to amino acid deficiencies or as an adjuvant in the treatment of herpes simplex virus infections due to its potential antiviral properties.
When used as a dietary supplement for humans, the dosage usually depends on age, gender, and specific health conditions. Generally, for adults, the recommended daily intake is around 1-3 grams. It can be taken orally with water, preferably after meals to enhance absorption. For children, the dosage should be adjusted according to their age and body weight, and it is advisable to consult a doctor or a nutritionist first.
In the animal feed industry, the amount of L-lysine monohydrate added to the feed is determined by the type of animals, their growth stage, and the existing nutrient content in the feed. Professional feed formulation software or the advice of animal nutrition experts can be used to determine the appropriate dosage. It should be thoroughly mixed with other feed ingredients to ensure uniform distribution.
In pharmaceutical applications, it is used according to the specific formulation and instructions of the drug. It may be included in tablets, capsules, or liquid formulations, and patients should follow the doctor's prescription strictly.
Case 1: Human Dietary Supplement
A middle - aged man with a sedentary lifestyle and a diet low in protein started taking L-lysine monohydrate supplements at a dosage of 2 grams per day. After a few weeks, he reported an increase in energy levels and a reduction in muscle fatigue. His overall immune function also seemed to improve, as he caught fewer colds during the following winter season.
Case 2: Animal Feed
A poultry farm added L-lysine monohydrate to the feed of their broiler chickens. The chickens showed significantly better growth rates compared to the previous batch without the lysine supplement. The feed conversion ratio improved, meaning less feed was needed to produce the same amount of body weight gain. As a result, the farm's profitability increased, and the quality of the chicken meat was also enhanced.
Case 3: Pharmaceutical Application
A patient suffering from recurrent herpes simplex virus infections was prescribed a drug containing L-lysine monohydrate. After a course of treatment, the frequency and severity of the outbreaks were significantly reduced. The patient reported fewer painful blisters and a quicker recovery time between episodes.
