L-Tryptophan

Description

L-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 exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. L-Tryptophan exists in all living species, ranging from bacteria to humans. L-Tryptophan participates in a number of enzymatic reactions, within cattle. In particular, L-Tryptophan can be converted into n'-formylkynurenine; which is catalyzed by the enzyme tryptophan 2,3-dioxygenase. In addition, L-Tryptophan and tetrahydrobiopterin can be converted into 5-hydroxy-L-tryptophan and 4a-hydroxytetrahydrobiopterin through the action of the enzyme tryptophan 5-hydroxylase 1. In cattle, L-tryptophan is involved in the metabolic pathway called the tryptophan metabolism pathway. L-Tryptophan is a potentially toxic compound. L-Tryptophan has been found to be associated with several diseases known as pancreatic cancer, tryptophanuria with dwarfism, crohn's disease, and alzheimer's disease; also l-tryptophan has been linked to the inborn metabolic disorders including hartnup disease.
