  • Experimental Physico-chemical Properties
  • Miscellaneous
    • Chemical Class:

      A cyclic nonapeptide hormone with amino acid sequence CYIQNCPLG that also acts as a neurotransmitter in the brain; the principal uterine-contracting and milk-ejecting hormone of the posterior pituitar y. Together with the neuropeptide vasopressin, it is believed to influence social cognition and behaviour. ChEBI, CHEBI:7872
    • Bio Activity:

      <p>Oxytocin is a reproductive hormone and neuropeptide which is involved in reproduction and many other physiological and pathophysiological processes.</p> Hello Bio HB2929
