Tryptophan (symbol Trp or W) 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. Tryptophan is also a precursor to the … See more Amino acids, including tryptophan, are used as building blocks in protein biosynthesis, and proteins are required to sustain life. Tryptophan is among the less common amino acids found in proteins, but it plays … See more Depression Because tryptophan is converted into 5-hydroxytryptophan (5-HTP) which is then converted into the neurotransmitter serotonin, it has been proposed that consumption of tryptophan or 5-HTP may improve depression … See more Tryptophan taken as a dietary supplement (such as in tablet form) has the potential to cause serotonin syndrome when combined with … See more As an essential amino acid, tryptophan is not synthesized from simpler substances in humans and other animals, so it needs to be present in the diet in the form of tryptophan-containing proteins. Plants and microorganisms commonly synthesize tryptophan from See more In 2002, the U.S. Institute of Medicine set a Recommended Dietary Allowance (RDA) of 5 mg/kg body weight/day of Tryptophan for adults 19 years and over. Dietary sources See more Potential side effects of tryptophan supplementation include nausea, diarrhea, drowsiness, lightheadedness, headache, dry mouth, blurred vision, sedation, euphoria, and nystagmus (involuntary eye movements). See more The isolation of tryptophan was first reported by Frederick Hopkins in 1901. Hopkins recovered tryptophan from hydrolysed casein, recovering 4–8 g of tryptophan from 600 g of crude casein. See more WebMay 25, 2024 · Among the 20 amino acids needed for protein synthesis, Tryptophan (Trp) is an aromatic amino acid fundamental not only for the synthesis of the major components of living cells (namely, the proteins), but also for the maintenance of cellular homeostasis. During the evolution, most organisms stopped producing 9 of 20 amino acids and thus …
