SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Use local exhaust or breathing protection. Fresh air, rest.
Skin Redness. Burning sensation. Itching. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain. Wear safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion Abdominal pain. Nausea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
Description L-Tyrosine is a non-essential amino acid which can inhibit citrate synthase activity in the posterior cortex.
Target Human Endogenous Metabolite
In Vitro Results show that L-Tyrosine in vitro inhibits citrate synthase activity in the posterior cortex (2.0 and 4.0 mM), malate dehydrogenase is not altered by L-Tyrosine and succinate dehydrogenase is increased in the posterior cortex (0.1, 1.0, 2.0 and 4.0 mM), hippocampus (1.0, 2.0 and 4.0 mM), striatum (4.0 mM) and liver (0.1, 1.0, 2.0 and 4.0 mM). When complex I activity is analyzed, inhibition is observed in hippocampus (4.0 mM). In addition to inhibition in the hippocampus, complex II also is inhibited in the posterior cortex (0.1, 1.0, 2.0 and 4.0 mM) and liver (1.0, 2.0 and 4.0 mM). For complex II–III, activity is not altered by L-Tyrosine, and complex IV activity has decreased in the posterior cortex (1.0, 2.0 and 4.0 mM) following treatment with L-Tyrosine[1].

Product Description
L-Tyrosine is a naturally occurring amino acid that is commonly used in the food industry as a food additive. It is a non-essential amino acid, which means that the body can synthesize it from other amino acids.
As a food additive, L-Tyrosine is primarily used as a flavor enhancer and to improve the texture of processed foods. It has a slightly bitter taste and is often added to food products, such as soups, sauces, and dressings, to enhance their flavor. L-Tyrosine also acts as a stabilizer and emulsifier in food processing, helping to improve the texture and appearance of various food products.
L-Tyrosine is generally regarded as safe for consumption in small amounts and is well-tolerated by most people. It is also found naturally in many foods, including meats, dairy products, and legumes.
In addition to its use as a food additive, L-Tyrosine is also available as a dietary supplement. It is often marketed as a supplement that can help support healthy brain function and improve cognitive performance, as well as promote better mood and reduce stress.
Overall, L-Tyrosine is a valuable food additive that provides a range of benefits to the food industry. It is commonly used in processed foods to enhance their flavor and improve their texture, and is generally safe for consumption in small amounts. As with any food additive or dietary supplement, it is important to use L-Tyrosine in moderation and in accordance with industry guidelines to ensure its safety and efficacy.
