Factory Supply L-Selenomethionine CAS 3211-76-5
What is L-Selenomethionine?
L-selenomethionine is a white to off-white chiral amino acid powder that is stable at room temperature, soluble in water and alcoholic solvents, and insoluble in ethers. It possesses typical amino acid physicochemical properties (as well as the unique activity of selenium). As the most important organic selenium form in nature, its L-configuration has high bioavailability and can significantly enhance glutathione peroxidase expression, exhibiting antioxidant, immunomodulatory, and reproductive benefits (such as enhancing sperm motility). It can be used as a safe and effective selenium supplement for human nutrition and as a feed additive in livestock and poultry farming to boost immunity and fertility. Furthermore, as a model compound for active amino acids, it is widely used in basic biochemical research.

What are the effects of L-selenomethionine?
1. Antioxidant and anti-inflammatory
L-selenomethionine neutralizes free radicals and reduces the damage of oxidative stress to cells by participating in the synthesis of glutathione peroxidase (GPX). This antioxidant ability can delay aging, reduce the risk of chronic inflammation, and fight oxidative damage caused by external factors such as environmental pollution or ultraviolet rays.
2. Enhance immune function
Selenium is an important factor in the activation of immune cells (such as T cells and natural killer cells). Essential elements for the body. L-selenomethionine can regulate immune responses and help the body resist viral and bacterial infections. Studies have shown that selenium deficiency may increase susceptibility to diseases such as influenza and hepatitis, and appropriate supplementation can improve immune function.
3. Thyroid hormone metabolism support
The thyroid gland is one of the organs with the highest selenium content. L-selenomethionine participates in the deiodination process of thyroid hormones (T4 converted to active T3) to maintain hormone balance. Selenium deficiency may lead to an increased risk of hypothyroidism or autoimmune thyroiditis (such as Hashimoto's thyroiditis).
4. Detoxification and metabolism promotion
Selenium and heavy metals (such as Mercury, lead) has a strong affinity, can form a complex and accelerate its excretion. In addition, L-selenomethionine helps remove toxins by supporting the activity of detoxification enzymes in the liver, and participates in amino acid metabolism to maintain normal protein synthesis.
5. Other benefits
Cardiovascular protection: Selenium may reduce the risk of atherosclerosis by reducing the level of oxidized low-density lipoprotein (LDL).
Neuroprotection: The antioxidant properties of selenium may have a potential protective effect on neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.
Reproductive health: Selenium is required for male sperm formation, and appropriate supplementation may improve sperm quality.
Real-World Applications of L-Selenomethionine
Nutritional Fortification
Selenoproteins (selenomethionine) have become national food safety standards, and selenocysteine (MSC) has become a new-generation selenium supplement due to its high bioavailability.
Agricultural Innovation
In a Cherry Valley meat breeder duck experiment, supplementing selenomethionine increased egg fertility and reduced embryonic mortality. A feeding trial with young goats showed that the organic selenium group increased muscle selenium deposition and reduced shear stress, significantly improving meat tenderness.
Drug Development
Nanomedicines modified with selenoamino acids exhibit unique advantages in targeted delivery. In anti-epileptic drug development, selenocysteine analogs reduce epileptic seizure frequency by modulating GABAergic neuron activity.
