Oxytocin Acetate | Research Use Only

What it is

Oxytocin acetate is the acetate salt form of oxytocin, a synthetic preparation of the endogenous nonapeptide hormoneoxytocin. In the scientific literature, oxytocin is widely described as a hypothalamic peptide hormone that signals through the oxytocin receptor (OXTR), which is why it is commonly studied in receptor biology, neuroendocrine signaling, and smooth-muscle response research.

Origins and scientific context

Oxytocin is not a lengthened analog like some modified research peptides, but rather a synthetic version of the native oxytocin sequence itself. DailyMed describes oxytocin injection as a synthetic polypeptide, while receptor and signaling reviews explain that oxytocin acts through OXTR, a G protein-coupled receptor expressed in central and peripheral tissues.

Molecular profile

DailyMed lists oxytocin with the empirical formula C43H66N12O12S2 and a molecular weight of approximately 1007.19 g/mol. Oxytocin is classically identified as a nine-amino-acid peptide containing an intramolecular disulfide bond, and acetate-form product listings reflect the salt form used in research and formulation contexts.

Scientific overview

In simplified terms, oxytocin acetate is used in research to study OXTR signaling, neuroendocrine communication, and downstream intracellular pathway activation. Reviews of the oxytocin system describe broad signaling involvement across calcium mobilization, MAPK-related pathways, and tissue-specific receptor responses in both central and peripheral experimental models.
