L-tyrosine (Tyr) plays an important role in human and animal metabolism, growth, and development, and is widely used in food, feed, medicine and chemical industries. It is often used as a nutritional supplement for phenylketonuria patients, and as a raw material for the preparation of polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, p-hydroxy styrene and other pharmaceutical and chemical products. However, with the discovery of more high-value L-tyrosine derivatives such as danshensu, resveratrol and hydroxytyrosol in vivo, L-tyrosine is increasingly developing towards platform compounds.
1. Important intermediates: intermediates of derivative products of L-tyrosine series, including 3,4-dihydroxy-L-phenylalanine (L-DOPA), melanin, coumaric acid, etc., are not only widely used in medicine, chemical industry and other fields, but also raw materials of various chemical products. L-DOPA is an effective drug for Parkinson's disease; The physicochemical properties of melanin enable it to be used as an ultraviolet absorber, cation exchanger, drug carrier, etc; Coumaric acid is an important component of some novel complexes, coatings and adhesives.
2. Amino acid drugs and nutritional supplements: L-tyrosine is the raw material of amino acid infusion and amino acid compound preparation as a nutritional supplement. It is used to treat poliomyelitis and tuberculous encephalitis/hyperthyroidism.
1. Purer appearance and color: Viablife's L-Tyrosine is a pure white powder with uniform particle size.
2. Higher purity: Biosynthetic L-Tyrosine, with higher purity and fewer impurities.
3. Strong supply capacity: Viablife's L-Tyrosine supply capacity can reach 1000 tons.
4. The lower price: The price of L-tyrosine is 5%~10% lower than that of our competitors.
L-Tyrosine (Levodopa EP Impurity B) is one of the 22 proteinogenic amino acids that are used by cells to synthesize proteins. L-Tyrosine is biologically converted from L-phenylalanine and is in turn converted to L-DOPA and further converted into the neurotransmitters: dopamine, and epinephrine.
1. Patients with vitiligo who eat food containing L-tyrosine can promote the formation of melanin, which can play a role in relieving the symptoms of vitiligo.
2. L-Tyrosine, as a non-essential amino acid, can regulate emotions, help speed up the metabolism of the body, and also help regulate appetite.
3. It can prevent anxiety, depression and chronic fatigue.
Properties: white needle crystal or crystalline powder, odorless, bitter taste.
Solubility: insoluble in anhydrous ethanol, ether and acetone, soluble in dilute acid or base.
There are two main industrial production methods of L-tyrosine.
① One is to extract protein hydrolysate by chemical method, but the chemical process is complicated, the conversion rate of products is low, and there are problems such as high cost and serious environmental pollution.
② The other is to use tyrosine phenol lyase to catalyze the synthesis of tyrosine from phenol, pyruvic acid, ammonia and other substrates. However, due to the need for relatively expensive raw materials, complex reaction conditions and processes, the production cost is still high.
Viablife Biotech chooses the biosynthetic technology independently developed, and provides customers with high-quality and stable L-tyrosine products through strict strain screening and advanced automatic processing technology.

Viablife has built a platform with independent Intellectual Property rights called Viablife Biolego®. Tens of products have been developed and delivered to our clients through this platform. At the same time, we also build Viablife Biolego Factory® which is an intelligent manufacturing center. On the basis of Bionics principles, we divide complex manufacturing processes into several processing modules. Similar to a Multi-processing CPU, each processing module can work simultaneously to form a powerful manufacturing capacity. On Viablife Biolego Factory®, we select a series of products that are our featured products, these products can be produced by all the processing modules or part of the whole processing modules. On top of that, we employ AI data analysis to help develop and distribute tasks for all processing modules to ensure a consistent and stable supply of products.
