α-hypophamine

Oxytocin (Syntocinon) is a mammalian neuropituitary hormone, a pleiotropic hypothalamic peptide and ligand for the oxytocin receptor, which contributes to labor, lactation, and pro-social behavior. Oxytocin has the ability to stimulate mammary secretion of breast milk, promote contraction of uterine smooth muscle during labor, and facilitate mothering.

Oxytocin acetate (α-Hypophamine acetate) is a mammalian neurohypophysial hormone, a ligand of oxytocin receptor.
