Structural correlation between met-enkephalin, an opioid peptide (left), and morphine, an opiate drug (right) Opioid peptides or opiate peptides are peptides that bind to opioid receptors in the brain; opiates and opioids mimic the effect of these peptides. Such peptides may be produced by the body itself, for example endorphins. The effects of ...
Activation of the μ-opioid receptor by an agonist such as morphine causes analgesia, sedation, slightly reduced blood pressure, itching, nausea, euphoria, decreased respiration, miosis (constricted pupils), and decreased bowel motility often leading to constipation. Some of these effects, such as analgesia, sedation, euphoria, itching and ...
In addition to endomorphins, morphine and morphine-like opiates target the μ-opioid receptor. Thus, endomorphins pose significant potential as analgesics and morphine substitutes. [ 4 ] In vitro assessment of endomorphins as analgesics reveals similar behavior to morphine and other opiates, where drug tolerance leads to dependence and addiction.
Endorphins are generally known as neurotransmitters that are released when the body goes into pain. [3] The three endorphins that play a role in this response are α-endorphin, β-endorphin (beta-endorphin), and γ-endorphin (gamma-endorphin) which are all derived from the same polypeptide known as pro-opiomelanocortin.

Endorphins may contribute to the positive effect of exercise on anxiety and depression. [43] The same phenomenon may also play a role in exercise addiction . Regular intense exercise may cause the brain to downregulate the production of endorphins in periods of rest to maintain homeostasis , causing a person to exercise more intensely in order ...
β-Endorphin (beta-endorphin) is an endogenous opioid neuropeptide and peptide hormone that is produced in certain neurons within the central nervous system and peripheral nervous system. [1]
Similar to other endorphins, research focusing upon γ-endorphin has been ongoing since its discovery in the 1970s. Yet, most of the information about the substance's exact role within the body is speculation that has yet to be proven.
