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. L-Tryptophan is found, on average, in the highest concentration in a few different foods, such as caseins, steller sea lions, and evening primroses and in a lower concentration in pak choy, amaranths, and highbush blueberries. L-Tryptophan has also been detected, but not quantified in, several different foods, such as malabar plums, grapefruit/pummelo hybrids, tartary buckwheats, lemon verbena, and sea-buckthornberries. This could make L-tryptophan a potential biomarker for the consumption of these foods. L-Tryptophan is a potentially toxic compound.
