Morphology

enkephalin = encephalon (semi-transparent) = enkephal + in

Built from the brain-combining form (encephal-/enkephal-) plus the protein suffix '-in', which indicates a brain-related peptide but requires biomedical knowledge to fully interpret.

Etymology

Enkephalin comes from Greek parts en- meaning 'in' and kephale meaning 'head', with the protein ending -in like in insulin. So the name literally says 'in the head' and helps you remember that enkephalin is a natural brain chemical that works in the brain and spinal cord to help reduce pain.
