Description
Sources: https://www.drugbank.ca/drugs/DB00150
Curator's Comment: description was created based on several sources, including https://www.drugs.com/tryptophan.html

Tryptophan is alpha-aminoacid that is used in the biosynthesis of proteins. It is essential aminoacid in humans, meaning the body cannot synthesize and it must be obtained from the diet. Tryptophan is a precursor of serotonin, and as such is sold over the counter in many countries as a dietary supplement for use as an antidepressant, anxiolytic and sleep aid, however application of tryptophan in these indications is not approved by FDA.

Depression 235 Sources: http://www.mhra.gov.uk/home/groups/par/documents/websiteresources/con454366.pdf	Primary		Approved 8429	OPTIMAX Approved Use Optimax capsules are used only in combination with other anti-depressants when these anti-depressants have been used alone in a patient for a period of time but have not been sufficiently effective. Launch Date 1.40460478E12
Anxiety 267 Sources: http://www.mhra.gov.uk/home/groups/par/documents/websiteresources/con454366.pdf	Primary		Approved 8429	OPTIMAX Approved Use Optimax 500 ing capsules contain L-tryptophan winch is found naturally in animal and plant proteins. L-tryptophan is considered an essential amino acid because our bodies can't make it. It is important for the development and functioning of many organs in the body. After absorbing L-tryptophan from food, our bodies convert it to 5-HTP (5-liydroxytryptophan) and then to serotonin which reduces feelings of anxiety and depression. Launch Date 1.40460478E12

Sample Use Guides

In Vivo Use Guide

As a dietary supplement, tryptophan is administered orally with tryptophan-reach food (turkey, eggs, beans) or as dietary supplements in the form of tablets.

Route of Administration: Oral

In Vitro Use Guide

Tryptophan hydroxylase activity was assayed in a low-speed supernatant fraction of cerebral cortex or midbrain from a single rat. The enzyme preparation contained 2 mM dithiothreitol and had been subjected to gel filtration to remove small molecules. The assay was carried out in the presence of 200 uM L-tryptophan and 50 gM DL-6-methyl-5,6,7,8-tetrahydropterin.
