Mechanism record

Oxytocin is a cyclic 9-residue chemical sequence hormone (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂, 1↔6 disulfide) synthesized in hypothalamic paraventricular and supraoptic nuclei. It binds the oxytocin receptor (OXTR), a Gq-coupled GPCR, activating PLC/IP3/DAG cascades. Central effects include anxiolysis, social bonding, and stress-axis modulation via HPA suppression. Peripheral effects include uterine contraction and milk ejection.

Limitations and research boundary

Research use only. Not for human or veterinary use. Public catalog information is limited to chemical identity, analytical documentation, and external reference records.

External records are attributed references. Their presence does not convert a source-reported observation into a product claim.
