The neurotransmitter serotonin.

Ball-and-stick model of 5-hydroxytryptamine. Grey balls represent carbon atoms; blue balls represent nitrogen atoms; red balls represent oxygen atoms; and white balls represent hydrogen atoms.

The neurotransmitter serotonin.

Skeletal formula of serotonin, C10H12N2O. Structure based on X-ray crystallographic determination from Acta Chem. Scand. (1978) 32a, 267–270. Structure originally drawn in ChemBioDraw Ultra 12.0 by Ben Mills. It was then manually retraced with Inkscape.

The neurotransmitter serotonin.

Ball-and-stick model of the serotonin molecule, C10H12N2O. Colour code: Carbon, C: grey-black Hydrogen, H: white Nitrogen, N: blue Oxygen, O: red Structure based on that found in the salt serotonin hydrogen oxalate, determined by X-ray crystallography in Acta Chem. Scand. (1978) 32a, 267-270. Model manipulated in CrystalMaker 8.3. The structure of the serotonin cation from the above crystal structure was opened in Spartan Student 4.1, one hydrogen atom on the RNH3+ group was deleted, yielding the neutral serotonin molecule. Its structure was then refined with Hartree-Fock level of theory and the 3-21G basis set. Image generated in Accelrys DS Visualizer.
