L-tyrosine, also known as (2S,3R) -2-amino-3-P-hydroxymethylpropionic acid, the molecular formula is C9H11NO3, the molecular weight is 181.19, CAS number is 60-18-4, the appearance is white needle-like crystal or crystalline powder, odorless, but bitter.
L-tyrosine is an aromatic amino acid, which naturally exists in various proteins. Among them, milk is rich in casein. For humans and animals, L-tyrosine is an important amino acid, playing an important role in our metabolism and growth and development.
L-tyrosine is mainly used as nutritional enhancer and moisturizer in dairy products, feed, medicine, daily chemicals and other fields, and can also be used in biochemical research. In the field of biochemical research, L-tyrosine can not only be used as a standard for the determination of nitrogen in polypeptides, but also can be used for colorimetric quantitative analysis of Milon reaction. In addition, L-tyrosine can also be used to prepare tissue culture medium as a precursor of dopamine and catecholamine.
