Context examples:
This species is oxidase positive, negative for urease, phenylalanine deaminase and tryptophan deaminase, is unable to grow on solid medium at 4 to 10 degrees C, and is relatively halointolerant.
(Moraxella atlantae, NCI Thesaurus)
Sustained administration of flerobuterol, similar to other beta-adrenergic agonists, may increase serotonin (5-HT) synthesis, thereby enhance serotonergic neurotransmission, partially through an increased transport of the serotonin precursor (tryptophan) to brain.
(Flerobuterol, NCI Thesaurus)
This bacteria is motile by a single polar flagellum, oxidase and catalase positive, chemoorganotrophic, gelatinase positive and can grow on L tryptophan culture.
(Acidovorax facilis, NCI Thesaurus)
An orally bioavailable, tryptophan hydroxylase (TPH) inhibitor prodrug labeled with carbon C 14, which could be used to evaluate the pharmacokinetic profile of telotristat etiprate.
(Carbon C 14 Telotristat Etiprate, NCI Thesaurus)
Endogenous oxitriptan is produced from the essential amino acid L-tryptophan.
(Oxitriptan, NCI Thesaurus)
The amino acids alanine, glycine, serine, cysteine, tryptophan and threonine all have a common endpoint, the metabolic intermediate pyruvate.

Alanine is one of the most common residues for protein synthesis and is involved in the metabolism of tryptophan and vitamin pyridoxine.
(DL-Alanine, NCI Thesaurus)
Collagen is differentiated from other fibrous proteins by its content of proline, hydroxyproline, and hydroxylysine; by its absence of tryptophan; and by its high content of polar groups.
(Collagen Gene, NCI Thesaurus)
A small non-essential amino acid in humans, Alanine is one of the most widely used for protein construction and is involved in the metabolism of tryptophan and vitamin pyridoxine.
(Alanine, NCI Thesaurus)
A radiopharmaceutical containing an analogue of tryptophan, alpha-methyltryptophan (AMT), labeled with carbon 11 (11C), used to measure serotonin synthesis in the human brain using positron emission tomography (PET).
