Description D-Tyrosine is the D-isomer of tyrosine. D-Tyrosine negatively regulates melanin synthesis by inhibiting tyrosinase activity. D-Tyrosine inhibits biofilm formation and trigger the self-dispersal of biofilms without suppressing bacterial growth[1][2].
Target Tyrosinase[1]
In Vitro DL-Lysine (Lys) is a high affinity, basic amino acid substrate for amino acid transporter b0,+ with Km value ranging from 100-400 μM[1].

Product Description
D-tyrosine is a non-essential amino acid that has numerous applications in the pharmaceutical, cosmetic, and food industries. In this article, we will analyze the product from the perspectives of its medical uses, upstream and downstream of the industry, market trends, and chemical suppliers.

Medical Uses:
D-tyrosine is a vital component in the synthesis of several important neurotransmitters, such as dopamine and norepinephrine. It can be used in the treatment of Parkinson's disease, depression, and attention deficit hyperactivity disorder (ADHD).

Upstream and Downstream Industry:
D-tyrosine can be synthesized from the amino acid phenylalanine, which is obtained from natural sources like soybeans, meat, and dairy products. It is mainly produced using microbial fermentation technology. Downstream products of D-tyrosine include drugs, cosmetics, and supplements.

Market Trends:
The global D-tyrosine market is expected to grow in the coming years due to the increasing demand for nutritional supplements and functional foods. D-tyrosine is also widely used in the cosmetic industry, particularly in anti-aging products. The Asia-Pacific region is the largest market for D-tyrosine due to the growing population, increasing disposable income, and the rising demand for nutraceuticals.

Chemical Suppliers:
There are several key players in the D-tyrosine market, including Shanghai Soyoung Biotechnology Inc., Iris Biotech GmbH, and Taizhou Crene Biotechnology Co., Ltd. These companies are engaged in the production and distribution of D-tyrosine for various industrial applications.

Conclusion:
In summary, D-tyrosine is a versatile amino acid with significant medical, industrial, and commercial value. As the demand for nutraceuticals and anti-aging products continues to rise, the global D-tyrosine market is expected to grow in the coming years.
