Details
Tryptophan
(IUPAC-IUBMB abbreviation: Trp or W; IUPACabbreviation: L-Trp or
D-Trp; sold for medical use as Tryptan) is one of the 22standard
amino acids and an essential amino acid in the human diet,
asdemonstrated by its growth effects on rats. It is encoded in the
standardgenetic code as the codon UGG. Only the L-stereoisomer of
tryptophan is used instructural or enzyme proteins, but the R
-stereoisomer is occasionally found innaturally produced peptides
(for example, the marine venom peptide contryphan).The
distinguishing structural characteristic of tryptophan is that it
containsan indole functional group.
