Chemical Information
FooDB NameL-Tryptophan
DescriptionL-Tryptophan, also known as Trp or W, belongs to the class of organic compounds known as indolyl carboxylic acids and derivatives. Indolyl carboxylic acids and derivatives are compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an indole ring. L-Tryptophan is a very strong basic compound (based on its pKa). L-Tryptophan exists in all living species, ranging from bacteria to humans. Within humans, L-tryptophan participates in a number of enzymatic reactions. In particular, L-tryptophan can be converted into n'-formylkynurenine through the action of the enzyme tryptophan 2,3-dioxygenase. In addition, L-tryptophan and tetrahydrobiopterin can be converted into 5-hydroxy-L-tryptophan and 4a-hydroxytetrahydrobiopterin through its interaction with the enzyme tryptophan 5-hydroxylase 1. The L-enantiomer of tryptophan. In humans, L-tryptophan is involved in tryptophan metabolism. Outside of the human body, L-Tryptophan is found, on average, in the highest concentration within a few different foods, such as caseins, steller sea lions, and evening primroses and in a lower concentration in thunnus, kefirs, and garden onions. L-Tryptophan has also been detected, but not quantified in, several different foods, such as thistles, gelatins, garden onion (var.), alpine sweetvetchs, and remoulades. This could make L-tryptophan a potential biomarker for the consumption of these foods.
