L-tyrosine is an amino acid that can be extracted from the hydrolysate containing protein substances such as casein or corn. This substance is also an essential amino acid for our human body. L-tyrosine appears as a colorless or white crystalline powder with molecular formula C9H11NO3, molecular weight 181.19, CAS number 60-18-4.
L-tyrosine is used for the treatment of hyperthyroidism in the medical field, and is mainly used as a food additive in the food field. In the biochemical field, it is used as an important reagent, and can also be used as the main raw material for the synthesis of antibiotics, peptide hormones, l-dopamine and other drugs.
Source of L – tyrosine in addition to the above description of the method of preparation of L – tyrosine and several other methods, such as using glucose as raw material, under the induction of a bacterium, L – tyrosine production bacteria fermentation can be L – tyrosine, also can be made of phenol, ammonia, pyruvic acid as raw materials, using beta tyrosinase catalysis L – tyrosine. L-tyrosine is one of the most widely used amino acids with many ways of preparation and wide application fields.
