n.
Any of a group of peptide hormones that bind to opioid receptors and act as neurotransmitters. Endorphins reduce the sensation of pain and affect emotions.

[endo(genous) + (mo)rphin(e).]

endorphin

(ɛnˈdɔːfɪn)
n
(Biochemistry) any of a class of polypeptides, including enkephalin, occurring naturally in the brain, that bind to pain receptors and so block pain sensation
[C20: from endo- + morphine]

en•dor•phin

en·dor·phin

(ĕn-dôr′fĭn)
Any of a group of substances found in the nervous system, especially in the brain, that regulate the body's response to pain and other stimuli.
Did You Know? In the 1970s, scientists began to wonder why drugs like morphine could kill pain so effectively. Researchers knew that morphine attached to specific body molecules called receptors, so they reasoned that these receptors probably existed because the body itself had natural painkilling compounds that also bonded to those receptors. They searched and finally found proteins called endorphins, a word that combines endogenous, meaning "naturally occurring within the body," and morphine. When your body is under stress, it can produce endorphins so that you can still function under what would otherwise be exceptionally painful conditions. Many long-distance runners, for example, claim that after they run for a while they start to feel exceptionally happy, a condition sometimes called a runner's high. High levels of endorphins in response to the strain of running seem to be responsible for this state of mind.
