Application:	L-tryptophan has 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.
Biochem/physiol Actions:	Tryptophan (Trp) is a heterocyclic, essential amino acid associated with growth, reproduction and immunity. Increased availability of tryptophan is necessary for the regulation of mood, cognition and behavior. The uptake of tryptophan by the brain depends on the plasma ratio of Trp to all of the other large neutral amino acids. Higher the ratio, greater is the Trp uptake.
Other Notes:	Amino acid precursor of serotonin and melatonin
