what is L Tyrosine powder ?
L-tyrosine is an aromatic amino acid that exists in various proteins, particularly abundant in dairy casein, and contains phenol groups in its molecules. L-Tyrosine is a non essential amino acid and a raw material for various bodily products. L-Tyrosine can be converted into various physiological substances in the body through different metabolic pathways, such as dopamine, adrenaline, thyroxine, and melanin. These substances are closely related to nerve conduction and metabolic regulation control. L-tyrosine powder was discovered in 1846 from casein and is a white crystalline powder that crystallizes from water into needle like or sheet-like structures

What are the uses of L Tyrosine powder?
L Tyrosine powder has the following uses
Amino acid drugs. Raw materials for amino acid infusion and amino acid compound preparations,
As a nutritional supplement. Used to treat conditions such as poliomyelitis and tuberculous encephalitis/hyperthyroidism
After co heating with sugars and undergoing amino carbonyl reactions, special aromatic substances can be generated.
Biochemical research. The standard for determining nitrogen in amino acids. Prepare tissue culture medium. Perform colorimetric quantitative analysis using the Milon reaction (protein colorimetric reaction). It is the main raw material for synthesizing various peptide hormones, antibiotics, and other drugs, and is an amino acid precursor of dopamine and catecholamines.

What is the production method of L Tyrosine powder?
![]() |
The precipitate produced by neutralization of protein acid hydrolysates such as casein and silk is separated and dissolved in dilute ammonia water, neutralized to pH 5, and then recrystallized. The second crude crystallization solution of cysteine extracted from pig hair hydrolysate is stored below 20 ℃ for two days to precipitate tyrosine. After filtration, crude tyrosine can be obtained, which can also be refined to obtain L Tyrosine powder. The yield of pig hair is 1%. |
