DEFINITION

Classification: 530/302

Endorphins and enkephalins; related peptides:

(under subclass 300) Peptides containing at least half the amino acid residues in sequence of the polypeptide with the structure: [figure]

(1) Note. Physical Properties: Number of Residues [figure]

(2) Note. Physiological Properties: Endorphins, Morphine like action. Found in brain, cerebrospinal fluid, pituitary and other organs. Function as neuromodulators or transmitters. Enkephalins. Pentapeptides which mimic the action of morphine. Synthesized in the brain and pituitary possibly by degradation of endorphins.

(3) Note. Synonyms. (a) Endorphins: Endogenous opiates, opiod peptides. (b) Enkephalins: Morphine line factor, pituitary opiate peptide.

(4) Note. CA Registry Numbers of unmodified form:
