The mood chemical that mostly works as a gut bouncer, not a happiness pill.
means A neurotransmitter and hormone that regulates mood, digestion, sleep, and appetite, with roughly 90% of it made and used in the gut rather than the brain.
from Coined by the biochemists who isolated it in the 1940s, from 'sero-' (serum, the fluid part of blood) plus 'tonin' (from 'tone,' as in vascular tone) — because it was first found as a substance in blood serum that made blood vessels constrict, tightening their tone. Only later did scientists realize this same compound moonlights as a major brain and gut signaling molecule, long after the name was already locked in.
