Serotonin and Melatonin Synthesis | Tryptophan Metabolism

The video tutorial explains the synthesis of serotonin and melatonin, detailing the step-by-step enzymatic processes involved. It covers the roles of serotonin in mood, appetite, and sleep regulation, and melatonin in circadian rhythm synchronization. The tutorial highlights the importance of tryptophan, an essential amino acid, and the enzymes and cofactors required for the conversion of tryptophan to serotonin and subsequently to melatonin. Key vitamins such as B6 and B5, and cofactors like tetrahydrobiopterin and s-adenosyl-methionine, are emphasized for their roles in these biochemical pathways.
