Oxytocin necklace 3D | 18k gold vermeil
Oxytocin is the cyclic nonapeptide that du Vigneaud synthesised in 1953, the first total synthesis of a polypeptide. The disulfide-locked ring enforces the conformation that the OXTR receptor recognises. Two amino acid swaps make vasopressin out of the same chassis, which is why the two peptides cross-react at low levels.
The Science Behind Oxytocin
Oxytocin's affiliative effects in animal models laid the groundwork for human research. The prairie vole pair-bonding story remains one of the clearest cases. Prairie voles form monogamous pairs while their meadow vole relatives do not, and the difference correlates with oxytocin and vasopressin receptor distribution in the ventral striatum. In humans, intranasal oxytocin studies have shown effects on trust, generosity, and social gaze, but effect sizes are modest and replication has been mixed. Therapeutic use in autism remains an open question. Oxytocin also drives labour contractions and milk letdown through smooth-muscle and myoepithelial OXTR activation, making it a central peptide in obstetrics.
A Daily Reminder For
A piece for the people who work with it directly:
- neuroendocrinologists studying social bonding and stress
- obstetricians and reproductive medicine specialists
- structural biochemists working on peptide hormones
- behavioural neuroscientists and animal-model researchers
- anyone for whom the OXTR receptor is part of daily research
Often given alongside the silver oxytocin 3D as a same-design pair across two materials, or paired with the flat oxytocin in either material as a 3D-and-flat duo.

FAQ
Is this specific enough for a neuroendocrine researcher?
Yes. Oxytocin is a daily concept for anyone running labour wards, OXTR receptor research, social-cognition studies, or peptide-hormone work. The 3D format and gold vermeil register make it suit a milestone moment, particularly for someone for whom oxytocin has been a recurring subject of papers, lectures, or grant applications.
How is oxytocin different from vasopressin?
Two amino acids. Vasopressin and oxytocin both have nine residues and a single disulfide bridge between cysteines at positions one and six. They differ at positions three and eight: oxytocin has isoleucine and leucine, vasopressin has phenylalanine and arginine. The two peptides cross-react at each other's receptors at high concentrations, which is one reason vasopressin can produce uterine effects and oxytocin can drive a small antidiuretic response.
What is the size, material, and chain?
48 mm 3D pendant in 18k gold vermeil (sterling silver core with 2.5 micron gold plating), nickel-free. 45 cm gold vermeil chain with a 5 cm extender. Ships free worldwide via DHL Express in 1-5 business days, with all import duties prepaid. Comes in a ready-to-gift jewelry box with the 30-day “Love It or Return It” policy.
Is the gold version the same size as the silver?
Yes. The same 3D form is available in sterling silver at the same 48 mm size. Material is the only difference. Many buyers pair the silver and gold versions as a layering option, or as a his-and-hers gift between two researchers in the same field.
