18363710-12	2008	CONCLUSIONS: Alpha-MTrp PET suggests abnormal metabolism of tryptophan in the neocortex.	Tryptophan	60-70	lysosomal protein transmembrane 4 alpha	Homo sapiens	19-23	
1524723-1	1992	The procedure for measuring the brain serotonin synthesis rate in living brain using labelled alpha-methyl-L-tryptophan (alpha-MTrp), a tryptophan analog, is described.	Tryptophan	109-119	lysosomal protein transmembrane 4 alpha	Homo sapiens	127-131	
17318550-2	2007	Here, we assessed the effects of aging on the brain regional alpha-[(11)C]methyl-L: -tryptophan (alpha-[(11)C]MTrp) trapping rate constant (K*; microl.g(-1).min(-1)), which, with certain assumptions, could be taken as a proxy of 5-HT synthesis.	Tryptophan	81-95	lysosomal protein transmembrane 4 alpha	Homo sapiens	110-114	
11579128-1	2001	alpha-Methyl-L-tryptophan (alpha-MTrp) is an artificial amino acid and an analog of tryptophan (Trp), the precursor of the neurotransmitter serotonin (5-HT).	Tryptophan	15-25	lysosomal protein transmembrane 4 alpha	Homo sapiens	33-37	
11590969-5	2001	The rate at which labelled alpha-MTrp is trapped is converted to the rate of 5-HT synthesis by dividing it by a conversion factor, called the lumped constant, and multiplying it by the plasma-free tryptophan concentration.	Tryptophan	197-207	lysosomal protein transmembrane 4 alpha	Homo sapiens	33-37
