L-tyrosine is one of the amino acids, it is also our human body essential amino acids, can from casein, such as corn protein hydrolyzed material extracted, L-tyrosine appearance for crystalline powder, with a bitter taste, dissolved in acid, alkali solution, slightly soluble in water, insoluble in ethanol, ether, acetone, etc.
In the early stage, l-tyrosine was mainly produced by hydrolyzing protein, but this method was gradually phased out due to limited material sources, high complexity of the process and long cycle, and was replaced by microbial fermentation, extraction, chemical and other production methods.
At present, the application of L-tyrosine mainly involves medical treatment, biochemical research and other fields, L-tyrosine can be used to determine the standard of nitrogen in amino acids, using Millon reaction colorimetric quantitative analysis, but also can prepare tissue culture medium. In the medical field, it can be used as a variety of raw materials for medicine, but also as a nutritional supplement.
