serotonin = sero<serum> + ton<tone> + in<chemical suffix>
- sero (from serum): Refers to blood plasma, highlighting its discovery in blood serum.
- ton (from tone): Suggests its role in regulating vascular tone (initially identified as a vasoconstrictor).
- in (chemical suffix): Common suffix for organic compounds (e.g., insulin, adrenaline).
Etymology Origin:
Coined in 1948 by researchers Maurice Rapport and Arda Green, the name reflects serotonin’s dual origin: isolated from serum and its effect on vascular tone. The suffix -in classifies it biochemically. Initially linked to blood pressure, its broader role in the nervous system was later uncovered.
Low serotonin levels are often associated with depression.
Sunlight exposure can boost serotonin production.
The gut produces about 90% of the body’s serotonin.
Certain foods like bananas contain precursors to serotonin.
