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.
Tetrahydrobiopterin is a cofactor in the production of L-DOPA from tyrosine and 5-hydroxy-L-tryptophan from tryptophan, which must be supplemented as treatment in addition to the supplements for classical PKU. [citation needed] Other underlying causes of tetrahydrobiopterin deficiency are: [2] 6-Pyruvoyltetrahydropterin synthase (PTPS) deficiency
Eosinophilia–myalgia syndrome is a rare, sometimes fatal neurological condition linked to the ingestion of the dietary supplement L-tryptophan. [1] [2] The risk of developing EMS increases with larger doses of tryptophan and increasing age. [3] Some research suggests that certain genetic polymorphisms may be related to the development of EMS. [4]
Research suggests that rhodiola rosea may reduce stress, as well as depression and anxiety symptoms. 5-HTP, also known as 5-hydroxytryptophan, has been found to increase serotonin levels in the brain.
5-HTP is produced from the amino acid tryptophan through the action of the enzyme tryptophan hydroxylase. Tryptophan hydroxylase is one of the biopterin-dependent aromatic amino acid hydroxylases. Production of 5-HTP is the rate-limiting step in 5-HT (serotonin) synthesis. 5-HTP is normally rapidly converted to 5-HT by amino acid decarboxylase. [1]
Acute tryptophan depletion (ATD) is a technique used extensively to study the effect of low serotonin in the brain. [1] This experimental approach reduces the availability of tryptophan , an amino acid which serves as the precursor to serotonin.
[1] [2] The amino acids L-tryptophan and L-5-hydroxytryptophan (5-HTP; oxitriptan) are precursors of serotonin and melatonin, while the amino acids L-phenylalanine, L-tyrosine, and L-DOPA (levodopa) are precursors of dopamine, epinephrine (adrenaline), and norepinephrine (noradrenaline).
