L-Threonine Amino Acid Powder Threonine CAS 72-19-5

L-Threonine is an essential amino acid that serves as a precursor to other amino acids such as glycine and serine. It plays vital roles in protein synthesis and various physiological functions in the body.

Specification:

  • Chemical Formula: C?H?NO?
  • Molecular Weight: 119.12 g/mol
  • Appearance: White crystalline powder
  • Solubility: Freely soluble in water
  • Melting Point: Approximately 256-266°C (492-511°F)
  • Specific Rotation: -26.7° to -29.4° (for the L-isomer)
  • Purity: Typically 98% or higher (may vary depending on the product)

 

Features:

  1. Essential Amino Acid: L-Threonine is an essential amino acid, meaning it cannot be synthesized by the body and must be obtained through diet or supplementation.
  2. Protein Synthesis: It is a key component in the synthesis of proteins and plays a vital role in supporting growth, tissue repair, and overall protein metabolism.
  3. Nutritional Supplement: L-Threonine is used as a dietary supplement to meet the nutritional requirements of animals and humans, especially in situations where the dietary intake may be insufficient.
  4. Sweet Taste: L-Threonine has a slightly sweet taste, which makes it suitable for use in food products where a mild sweetness is desired.
  5. Compatibility with Other Ingredients: L-Threonine is compatible with a wide range of other ingredients, allowing for its incorporation into various formulations and applications.
