Hello All,
Does anyone know what the suffix -orphin means? (Exorphins, endorphins...)
I "Googled" it and was unsuccessful in my search.
Cary -
endorphin (n.)
1975, from French endorphine, from endogène "endogenous, growing within" (see
endo- + genus) + (mo)rphine.
Looks like -"orphin" did not have a specific chemical meaning as a suffix, but
instead started with the word "endorphin" and then was modifed from there to
fit other similar compounds like exorphins. According to Wikipedia "Endorphins
("endogenous morphine") are endogenous opioid peptides that function as
neurotransmitters.[1] ". So the "-rphine" ending refers to the opiate
qualities of endorphins. You might find more if you looked at the history of
the discovery of endorphins. I don't know enough biochemistry to help you out
any further.
