Tryptophan, Serotonin, Tinnitus and the Chemistry of Depression
WebTakayoshi Ubuka, in Handbook of Hormones (Second Edition), 2024. Abstract. Serotonin is an indoleamine molecule that functions as a neurotransmitter. Tryptophan is hydroxylated at position 5 of the ring to form 5-hydroxytryptophan (5-HTP) by tryptophan hydroxylase, which is the rate-limiting step. 5-HPT is decarboxylated by 5-hydroxytryptophan decarboxylase … In animals, biosynthesis of melatonin occurs through hydroxylation, decarboxylation, acetylation and a methylation starting with L-tryptophan. L-tryptophan is produced in the shikimate pathway from chorismate or is acquired from protein catabolism. First L-tryptophan is hydroxylated on the indole ring by tryptophan hydroxylase to produce 5-hydroxytryptophan. This intermediate (5-H… phim the fruit of evolution
