Research profile
Social behaviour and neuroendocrine signalling
Human clinical research
What it is and why it is studied
Oxytocin is a cyclic nine-amino-acid peptide hormone. Oxytocin research explores links between neuroendocrine signals and social behaviour. A central question is how findings about this signalling system translate into measurable changes in specific populations.
What studies have found
The 24-week SOARS-B trial in children and adolescents with autism found no significant advantage for intranasal oxytocin over placebo on its primary social-function measure. Its secondary outcomes generally did not differ between groups either.
This result is important when assessing claims about bonding or social effects. The trial's population and preparation differ from a laboratory research vial.

The reference peptide has a disulfide bridge between cysteines 1 and 6 and a C-terminal amide.
Chemical information describes the named reference structure, not a batch analysis or confirmation of the material supplied. Counterions, water and excipients are excluded unless stated.
Understanding these details
A sequence describes the order of residues in a peptide. A molecular formula describes the atoms in the reference structure. Molar mass is expressed in grams per mole; it is not the amount in a vial. CAS numbers and PubChem identifiers help you find the corresponding chemical records.
