Linked from

The 15 pages that link to Tryptophan, each with the reason it gives.

• SerotoninNarrower topic: Serotonin synthesis begins with this dietary amino acid.

• TyrosineCompared with: Like tyrosine, it is aromatic, but its metabolic products and dietary status differ.

• IndoleRelated: It is a major biological source of the indole scaffold.

• PhenylalanineRelated: It is another essential aromatic amino acid used in proteins.

• PellagraRelated: This pathway can contribute to niacin supply, but cannot always prevent deficiency.

• NicotinamideRelated: It provides an alternative dietary starting material for making NAD and vitamin B3 equivalents.

• Nicotinic acidRelated: The body can make some vitamin B3 activity from tryptophan, reducing dependence on dietary niacin.

• ErythroseRelated: Its biosynthetic route begins with a shikimate-pathway intermediate derived partly from erythrose 4-phosphate.

• Glutaric acidRelated: A pathway of tryptophan degradation can also produce glutaric acid.

• Hartnup diseaseRelated: Poor tryptophan uptake can limit the body's production of niacin.

• Indole-3-acetic acidRelated: Many plants synthesize IAA through pathways that begin with tryptophan.

• TryptamineRelated: Decarboxylation of tryptophan produces tryptamine.

• Vitamin B3Related: Its conversion provides an additional route to make NAD beyond dietary B3.

• SkatoleRelated: Microbial breakdown of this amino acid can produce skatole.

• Anthranilic acidBroader topic: Anthranilate supplies the aromatic core from which organisms build tryptophan.
