Product Name: L-Tyrosine
CAS No.: 60-18-4
Appearance: White crystalline powder
Purity: 98%
Specifications: ISO 9001:2015 certified
Description:
L-Tyrosine is an aromatic amino acid found in various proteins, particularly abundant in casein from dairy products. It was first discovered by Liebig in 1846 from casein. L-Tyrosine is a white crystalline powder that crystallizes from water as needles or flakes. It is a non-essential amino acid, meaning it can be synthesized by the body, and serves as a precursor for several critical biochemical compounds, including dopamine, AD, thyroid hormones, and melanin.

Molecular Formula: C9H11NO3.
Molecular Weight: 181.19 g/mol.
Density: 1.456 g/cm3 (20°C).
Isoelectric Point: 5.66.
Melting Point:
L-form: Decomposes at 290-295°C (slow heating) or 314-318°C (rapid heating).
Racemic form: Decomposes at 290-295°C (slow heating) or 340°C (rapid heating).
Solubility: Soluble in water, ethanol, acids, and alkalis; insoluble in ether.
UV Absorption: Maximum absorption at 274 nm.
Color Reactions:
Reacts with diazotized C7H9NO3S to form an orange-red compound.
Turns purple or red with boiling dilute acetic acid and Na-NO3.
Turns yellow with warm H-NO3.
Forms a dark orange-yellow color with titanium dioxide in sulfuric acid.
Physiological Functions:
Precursor for Neurotransmitters and Hormones:
L-Tyrosine is metabolized into dopamine, no-repin-ephrine, and epin-ephrine, which are essential for neurotransmission and stress response.
It is also a precursor for thyroid hormones, which regulate metabolism.
Melanin Synthesis:
L-Tyrosine is involved in the production of melanin, the pigment responsible for skin, hair, and eye color.
Cognitive and Mood Support:
Supplementation with L-Tyrosine may improve cognitive performance, focus, and mood, especially under stress or fatigue.
Applications:
Pharmaceuticals:
Used in amino acid infusions and compound preparations for nutritional support.
Treats conditions such as polio, encephalitis, and hyperthyroidism.
Nutritional Supplements:
Added to dietary supplements for its role in neurotransmitter synthesis and stress management.
Biochemical Research:
Used as a standard for nitrogen determination in amino acids.
Essential for preparing culture media and conducting Millon's reaction for protein colorimetric analysis.
Food Industry:
Acts as a flavor enhancer when heated with sugars, producing unique aromatic compounds.
Usage:
Medical Use: Administered to support thyroid function, treat neurological disorders, and improve metabolic health.
Nutritional Supplements: Consumed to enhance cognitive function, mood, and stress resilience.
Research: Used in biochemical studies and as a reagent in laboratory analyses.
Packaging & Storage:
Store in a cool, dry place, protected from light and moisture.
Shelf life: 24 months under proper storage conditions.
Note: L-Tyrosine is a versatile amino acid with significant applications in medicine, nutrition, and research. Its role as a precursor for critical neurotransmitters and hormones makes it a valuable compound for supporting mental and physical health.
