[主题词] Opioid Peptides
[英文释义] The endogenous peptides with opiate-like activity. The three major classes currently recognized are the ENKEPHALINS,the DYNORPHINS,and the ENDORPHINS. Each of these families derives from different precursors,proenkephalin,prodynorphin,and pro-opiomelanocortin,respectively. There are also at least three classes of opioid receptors,but the peptide families do not map to the receptors in a simple way.
