代谢
5-HTP通过门脉循环运输到肝脏,在那里大约25%的给药剂量通过依赖维生素B6的L-芳香族氨基酸脱羧酶代谢为5-羟基色胺(5-HT)/血清素/。随后,5-HT代谢为5-羟基吲哚乙醛,这种物质会迅速代谢为5-羟基吲哚乙酸(5-HIAA)。
5-HTP is transported by the portal circulation to the liver where approximately 25% of an administered dose is metabolized via vitamin B6-dependent L-aromatic amino acid decarboxylase to 5-hydroxytryptamine (5-HT) /serotonin/. 5-HT is subsequently metabolized to 5-hydroxyindole acetaldehyde which is rapidly metabolized to 5-hydroxyindole acetaldehyde which is rapidly metabolized to 5-hydroxyindoleacetic acid (5-HIAA).
