Serotonin Function

Meaning

Serotonin function refers to the multifaceted biological roles of the monoamine neurotransmitter 5-hydroxytryptamine (5-HT), which regulates mood, sleep, appetite, and gastrointestinal motility, and critically modulates the endocrine system. As a key signaling molecule, its appropriate synthesis, release, and receptor binding are essential for psychological well-being and maintaining homeostatic balance, particularly in its complex interactions with stress hormones and sex steroids. Dysregulation of this function is clinically implicated in various mood disorders and certain endocrine pathologies.
