Description

L-Tyrosine is a non-essential, aromatic amino acid that serves as a crucial metabolic precursor for the synthesis of key neurotransmitters and hormones. Its significance lies in its role as a fundamental building block in both pharmaceutical synthesis and advanced nutritional formulations. This high-purity grade is essential for manufacturers in the pharmaceutical, nutraceutical, and research sectors who require a reliable and consistent raw material for critical applications.

Application

• Pharmaceutical Intermediates: A key starting material for the synthesis of L-DOPA (Levodopa), a primary treatment for Parkinson's disease.
• Dietary Supplements & Nutraceuticals: Used in formulations aimed at supporting cognitive function, mood regulation, and stress response due to its role in producing dopamine, norepinephrine, and epinephrine.
• Biochemical Research: Employed as a standard and reagent in cell culture media, enzymatic studies, and metabolic pathway analysis.
• Animal Nutrition: Incorporated into feed premixes to support protein synthesis and overall health in livestock and aquaculture.
• Cosmetic & Personal Care: Utilized in skincare products for its potential antioxidant properties and role in melanin synthesis.
