Chemical Description

  • L-Tryptophan, also known as β- Indolyl alanine, has the chemical formula C11H12N2O2.
  • It is one of the essential amino acids of the human body.
  • The appearance is white or yellowish crystal or crystalline powder, odorless and slightly bitter.
  • It is slightly soluble in water, very slightly soluble in ethanol, insoluble in chloroform, easily soluble in formic acid, and soluble in sodium hydroxide test solution or dilute hydrochloric acid.
  • It is a precursor to serotonin, a neurotransmitter that plays a key role in mood regulation and sleep.
  • It's used in the manufacture of medications and supplements intended to alleviate depression and insomnia.
  • It can be used in treatments aimed at preventing migraines, as serotonin is involved in the pathophysiology of migraines.
  • Due to its role in serotonin production, it can also be used in formulations designed to help manage chronic pain conditions.
  • As an essential amino acid, L-Tryptophan is included in dietary supplements to help ensure adequate intake, particularly for vegetarians and individuals with certain dietary restrictions.
  • It is sometimes added to foods to enhance their nutritional profile, especially in products aimed at promoting relaxation or better sleep, such as "night-time" teas or snacks.
  • Incorporated into foods that claim specific health benefits beyond basic nutrition, like improved mood or cognitive function.
  • It is added to animal feed to ensure optimal growth and development in livestock, poultry, and fish.
  • It's particularly important in swine and poultry feed to balance the amino acid profile, improve feed efficiency, and promote better growth rates.
  • It can help reduce stress in animals, particularly during transportation or weaning, which can improve overall animal welfare and productivity.
  • It is sometimes included in skin care formulations due to its role in protein synthesis and potential benefits in skin health and repair.
  • It is used in biotechnological processes involving the fermentation of certain microorganisms. These processes can produce various bioactive compounds and secondary metabolites important in pharmaceutical and agricultural industries.
  • Available in 1 Kg aluminum bags, 35 Kg bags and 25 Kg drums.
