What it is
Oxytocin is 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 pituitary. Together with the neuropeptide vasopressin, it is believed to influence social cognition and behaviour. It has a role as a vasodilator agent and an oxytocic. It is a heterodetic cyclic peptide and a peptide hormone. The listed molecular formula is C43H66N12O12S2. PepGrades separately preserves the catalog category because a chemical identity record does not establish a use, outcome, or product quality.
This label describes the available research record, not whether the compound is safe or effective for an individual.
