Serotonin (5-Hydroxytryptamine)

Build a molecular model of the hormone/neurotransmitter serotonin chemical compound (5-hydroxytryptamine) with genuine Molymod components from Indigo Instruments

The molecular structure of serotonin can be described as a 5-hydroxy derivative of tryptamine & or an indole ring with functional groups that include an amine (-NH₂) & hydroxyl (-OH). It is both a hormone & neurotransmitter found in animals ranging from mammals down to invertebrates. Compare it to psychoactive compounds such as THC, Ecstasy and LSD.

Serotonin's role as a neurotransmitter (CNS) is varied. It is involved in mood regulation and plays a key role in reducing depression, anxiety, and stress. Further, it acts on our sleep-wake cycle as a precursor to melatonin which in turn regulates sleep and circadian rhythms. Other neurotransmitter functions are modulation of learning, decision-making, and social behavior.

As a hormone, its role is more peripheral but 90% of serotonin is found in the gastrointestinal (GI) tract where it regulates gut motility and secretion. Its presence in the cardiovascular system affects vasoconstriction and blood clotting (platelet aggregation) while as an endocrine regulator it influences insulin secretion and metabolism.

A molecular model of Serotonin in the Molymod Hybrid Dome style uses the atoms & bonds in the parts list below. Our free 3D Molecular Model Builder shows other styles & allows for image rotation as an assembly guide.
