* * *en·dor·phin en-'dȯr-fən n any of a group of endogenous peptides (as enkephalin and dynorphin) found esp. in the brain that bind chiefly to opiate receptors and produce some of the same pharmacological effects (as pain relief) as those of opiates specif beta-endorphin
* * *n.one of a group of chemical compounds, similar to the encephalin, that occur naturally in the brain and have pain-relieving properties similar to those of the opiates. They are also responsible for sensations of pleasure. The endorphins are derived from a substance found in the pituitary gland known as beta-lipotrophin; they are thought to be concerned with controlling the activity of the endocrine glands.
* * *en·dor·phin (en-dorґfin) (enґdor-fin) [endogenous + morphine] any of three neuropeptides, amino acid residues of β-lipotropin; they bind to opioid receptors in the brain and have potent analgesic activity. β-Endorphin is the C-terminal 30â€“amino acid residue and is found in the adenohypophysis, hypothalamus, and other sites in the brain; one function appears to be mediation of pain perception. α-Endorphin and γ-endorphin are the N-terminal 16 and 17 amino acid residues, respectively. See also enkephalin and dynorphin.
