What is Tryptophan?

Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet. [1]


Plants and microorganisms commonly synthesize tryptophan from shikimic acid or anthranilate. [1]

The industrial production of tryptophan is also biosynthetic and is based on the fermentation of serine and indole using either wild-type or genetically modified bacteria such as B. amyloliquefaciens, B. subtilis, C. glutamicum or E. coli. [1]
