Endorphins

Endorphins

One of the three major groups of endogenous opioid peptides. They are large peptides derived from the pro-opiomelanocortin precursor. The known members of this group are alpha-, beta-, and gamma-endorphin. The term endorphin is also sometimes used to refer to all opioid peptides, but the narrower sense is used here; opioid peptides is used for the broader group.

Re: endorphins

I don’t quite know what you’re asking. The endorphins or enkephalins are small peptides. I wouldn’t expect much secondary or tertiary structure to be present. The one crystal structure that I’ve seen is an extended peptide with no additional secondary ...

The Fiber Disease

... But peptides are more direct in their action and properties. They may target specific functions. We have an example of small peptides like endorphins or enkephalins. Those peptides are approximately 30 amino acids long, and it is about 10 to 20 times [fewer] amino acids than in an average ...
