L-tryptophan is an essential amino acid which is necessary for normal growth in infants and for nitrogen balance in adults. It acts as a natural dietary supplement and used as an antidepressant, anxiolytic and sleep aid. It is used as a precursor to niacin, indole alkaloids and serotonin. It acts as an important intrinsic fluorescent probe, which finds to estimate the nature of microenvironment of the tryptophan.

L-tryptophan has also been used for the isolation of bone marrow–derived neutrophils. It has also been used to identify the use of Raman microscopy as a tool to study the network of neurons in pathologically normal retina.
