Tryptophan hydroxylase: a target for neuroendocrine disruption
Tryptophan hydroxylase (TPH; EC 1.14.16.4) is the rate-limiting enzyme in the synthesis of serotonin (5-hydroxytryptamine, or 5HT). 5HT is causally involved in numerous central nervous activities, and it has several functions in peripheral tissues, including the maintenance of vascular tone and gut motility.[supplied by OMIM] Disabling this enzyme with drugs (especially p-chlorophenylalanine aka PCPA and Fenclonine) h… WebFeb 21, 2024 · Data indicate that tryptophan hydroxylase (Tph)1-deficient mice, lacking non-neuronal serotonin, showed mild leukocytosis.

Serotonin (5-hydroxytryptamine, 5-HT) has a plethora of functions in both the central nervous system and the periphery. It is synthesized from tryptophan by the sequential action of two enzymes, tryptophan hydroxylase (TPH) and aromatic amino acid decarboxylase with TPH catalyzing the rate-limiting step. great work ethic quotes
