http://www.guidobauersachs.de/bc/trp.html WebTryptophan is an α-amino acid which is used in the biosynthesis of proteins and is encoded by the codon UGG. It is denoted as Trp or W. It consists of an α-carboxylic acid group, α-amino group, and a side chain indole, therefore making it a non-polar aromatic amino acid. It is required for humans but cannot be synthesized by the body.
