enkephalin

Pituitary hormones {encephalin} {enkephalin}| can have five-amino-acid opioid cores, bind to morphine-binding sites, and inhibit pain-information transmission. Enkephalins can acetylate, amidate, phosphorylate, glycosylate, and methylate. Methionine-enkephalin and leucine-enkephalin are peptides, act as opioids, and are in area postrema, locus coeruleus, medulla oblongata, pons, retina, superior olive, spinal cord, and ventral pallidum. Methionine-enkephalins are beta-endorphin precursors. Leucine-enkephalins are dynorphin precursors.

functions

Sympathetic-nervous-system enkephalins control blood vessels, regulate local blood flow and pressure, and cause analgesia.
