Tryptophan ball and stick model spinning. Tryptophan (symbol Trp or W) [3] is an α-amino acid that is used in the biosynthesis of proteins.Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent.

Structure of the trp operon. The trp operon is a group of genes that are transcribed together, encoding the enzymes that produce the amino acid tryptophan in bacteria. The trp operon was first characterized in Escherichia coli, and it has since been discovered in many other bacteria. [1]

As a single concrete data structure may be used to implement many abstract data types, some data structures may appear in multiple comparisons (for example, a hash map can be used to implement ...
L-Tryptophan to tryptamine – a trace amine neuromodulator; 5-HTP to serotonin (5-hydroxytryptamine) – a neurotransmitter; However, some of these reactions do not seem to bear much or any biological significance. For example, histamine is biosynthesised strictly via the enzyme histidine decarboxylase in humans and other organisms. [10] [11]
Later studies proposed that the reaction involves a condensation process, where glyoxylic acid combines with the indole group of tryptophan to form a complex quinonoid structure. This process explains the strong color change observed in the test and has been key to understanding tryptophan's chemical properties and its function in proteins.
The systematic name of this enzyme class is L-tryptophan indole-lyase (deaminating; pyruvate-forming). Other names in common use include L-tryptophanase, and L-tryptophan indole-lyase (deaminating). This enzyme participates in tryptophan metabolism and nitrogen metabolism. It has 2 cofactors: pyridoxal phosphate, and potassium. [1] [2] [3]
