L-tyrosine is not only an amino acid but also a non-essential amino acid in our body. It can be extracted from hydrolysate containing casein, corn, and other protein substances. It is a crystalline powder with a bitter taste, soluble in acid and base solution, slightly soluble in water, and insoluble in anhydrous ethanol, ether, acetone, etc. L-tyrosine molecular formula C9H11NO3, molecular weight 181.19, CAS number 60-18-4.
In the early stage, L-tyrosine was mainly produced by protein hydrolysis, but due to the limited source of raw materials, complex technology, and long production cycle, this method was gradually phased out and replaced by microbial fermentation, extraction, chemical methods, and other production methods.
At present, L-tyrosine is mainly used in medical, biochemical research, and other fields. We can use it as a standard for the determination of nitrogen in amino acids, colorimetric quantitative analysis with Milon reaction, and preparation of tissue medium. In addition, L-tyrosine is widely used in the field of medicine as a raw material for various drugs and nutritional supplements.
