Oxytocin, with the CAS number 24327-19-3, is a peptide hormone composed of nine amino acids, classified as a nonapeptide. It is produced in the hypothalamus and released by the posterior pituitary gland. Oxytocin plays a crucial role in various physiological processes, including childbirth, lactation, and social bonding. The structure of oxytocin includes a cyclic disulfide bridge formed between two cysteine residues, which contributes to its stability and biological activity. The specific designation "8-L-proline" indicates the presence of proline at the eighth position in its amino acid sequence, which is significant for its receptor binding and activity. Oxytocin functions by binding to its receptors, leading to smooth muscle contraction in the uterus during labor and facilitating milk ejection during breastfeeding. Additionally, it has been implicated in emotional and social behaviors, influencing trust and bonding between individuals. Due to its diverse roles, oxytocin is of interest in both medical and psychological research, particularly in the context of maternal health and social interactions.

The L8P variant of oxytocin is produced by the Cebidae family of New World monkeys. Intranasal application of the peptide, which binds to the OT and AVP V1 receptors, enhanced parental behavior in rats.
