Question

Quizplus · Accepted Answer

Opioids are derived from propeptides, which are longer chains of amino acids that are cleaved to produce smaller opioid peptides such as enkephalins, endorphins, and dynorphins. These peptides then bind to opioid receptors in the brain and spinal cord to produce their pain-relieving and mood-altering effects.
