Serotonin Molecular Structure - Neurotransmitter Chemistry Diagram #1207044 (License: Personal Use)

This 2D skeletal diagram depicts serotonin (5-hydroxytryptamine or 5-HT), a monoamine neurotransmitter derived from tryptophan. The molecule features an indole ring system with a hydroxyl group at position 5, a two-carbon linker, and a terminal dimethylamino group; the stereochemistry at the chiral center is shown as R-configuration. Its structure underpins interactions with multiple serotonin receptor subtypes (e.g., 5-HT1A, 5-HT2A) in the central and peripheral nervous systems.

Used in neuroscience, pharmacology, and biochemistry educational content, research articles, and medical websites to illustrate serotonin’s molecular architecture; matches user intent for learning about neurotransmitter chemistry, depression/anxiety mechanisms, or drug design (e.g., SSRIs).
