Serotonin and Melatonin Synthesis | Tryptophan Metabolism
Serotonin and melatonin are important neurotransmitters synthesized from the amino acid tryptophan. This article discusses the step-by-step process of serotonin and melatonin synthesis, enzymes involved, and cofactors required. It also covers the functions of serotonin and melatonin in the body.
Serotonin, also known as 5-hydroxytryptamine, is derived from tryptophan and plays a role in mood regulation, appetite, and sleep. Melatonin, produced from serotonin in the pineal gland, regulates the sleep-wake cycle. Tryptophan, an essential amino acid obtained from dietary sources like chocolate, milk, and poultry, is crucial for the synthesis of serotonin and melatonin.
The synthesis pathway involves enzymes such as tryptophan hydroxylase, aromatic L-amino acid decarboxylase, and serotonin N-acetyltransferase. Co-factors like tetrahydrobiopterin, pyridoxal phosphate (Vitamin B6), acetyl coenzyme A (Vitamin B5), and s-adenosylmethionine are necessary for these enzymatic reactions.
Understanding the synthesis pathway of serotonin and melatonin provides insights into the importance of specific nutrients for neurotransmitter production and overall health.
