What is L-Tryptophan?
L-tryptophan is the L-enantiomer of tryptophan. It has a role as a micronutrient, an antidepressant, a nutraceutical, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite and a human metabolite. It is a L-alpha-amino acid, a tryptophan, an erythrose 4-phosphate/phosphoenolpyruvate family amino acid and a proteinogenic amino acid. It is a conjugate base of a L-tryptophanium. It is a conjugate acid of a L-tryptophanate. It is an enantiomer of a D-tryptophan. It is a tautomer of a L-tryptophan zwitterion.
