Leírás

Alkalmazás

L-Tryptophan has been used as a nutritional supplement to study its effect on the circadian clock of primary cell lines. It has also been used as a test amino acid aerosol to study the variation in the fluorescence intensity of thermally-exposed bacterial bioaerosols.

Biokémiai/fiziológiai hatások

Tryptophan (Trp) is one of the functional amino acids that are associated with growth, reproduction, maintenance and immunity. Increased Trp availability is necessary for the regulation of mood, cognition and behaviour. It is hypothesised that L-Trp might be useful in inducing sleep in healthy adults against the normal circadian rhythm. Trp uptake by the brain depends on the plasma ratio of Trp to all of the other LNAAs (large neutral amino acids). Higher the Trp:LNAAs ratio, greater is the Trp uptake.
