Tryptophan Price Trend

During the fourth quarter of 2021, the pricing trend of amino acids in the Asian market shifted higher. Ex-Hyderabad Amino Acid prices increased from 2355.58 USD/MT to 2533.37 USD/MT in the Indian domestic market from October to December. Several Indian traders were dealing with a significant increase in the cost of imported materials, despite strong demand from the domestic downstream market. The manufacturing standstill in China owing to a coal shortage has had a significant impact on the Indian market, with numerous firms quoting out of stock for several amino acids. In addition, various manufacturing plants in China announced forced closures, affecting total product supplies in both China and India.

About Tryptophan:

Tryptophan is not only found in most proteins, but it also acts as a precursor of serotonin. Tryptophan is converted to 5-hydroxy-tryptophan (5-HTP), which in turn, is converted into serotonin, a neurotransmitter that is also essential in regulating appetite, sleep, mood, as well as pain. Tryptophan is a natural sedative which is present in dairy products, meats, brown rice, fish, and even in soybeans.

Chemical Formula of Tryptophan

  • Antidepressant

Production Process

  • Production of Tryptophan via Fermentation.

Tryptophan production at industrial level utilises biosynthesis and is based on the fermentation of serine and indole. The process involves the use of either wild-type or genetically modified bacteria such as B. amyloliquefaciens, C. glutamicum or E. coli. These microbial strains carry mutations and the conversion is catalysed by the enzyme tryptophan synthase
