L-Tryptophan

Description:

L-Tryptophan is an essential amino acid that plays a crucial role in protein synthesis and serves as a precursor for several important biomolecules, including serotonin, melatonin, and niacin. It is classified as a non-polar, hydrophobic amino acid due to its indole side chain, which contributes to its unique properties. L-Tryptophan is typically found in various dietary sources, such as meat, dairy products, nuts, and seeds. In terms of its chemical structure, it has a molecular formula of C11H12N2O2 and features an amino group, a carboxyl group, and an indole side chain. This compound is known for its role in mood regulation and sleep patterns, as it is involved in serotonin production. L-Tryptophan is also utilized in dietary supplements and is studied for its potential therapeutic effects in conditions like depression and insomnia. However, it is important to note that excessive intake can lead to side effects, and its supplementation should be approached with caution.

L-Tryptophan

CAS: 73-22-3

Tryptophan is a non-essential amino acid that has been shown to have an effect on mood, appetite, and sleep. L-Tryptophan is an essential amino acid. It is involved in the synthesis of serotonin and melatonin. The body breaks down tryptophan into 5-hydroxytryptophan (5HTP) and then into serotonin. Serotonin can be converted into melatonin by the pineal gland. Tryptophan levels are often low in people with depression and anxiety disorders. Tryptophan also has an effect on human gastrointestinal function, as it can stimulate gut motility and secretion of gastric acid and pepsinogen from the stomach lining. Tryptophan may also play a role in the discovery process, as it was found to increase the number of spontaneous oxidations in rat urine samples, which may be indicative of a new chemical reaction or drug discovery process.
