vasotocin

va·so·to·cin

(vā'sō-tō'sin, vas-ō-),
A nonapeptide hormone of the neurohypophysis of subvertebrates, with activities similar to that of vasopressin and oxytocin; chemically identical with human vasopressin except for an isoleucyl residue at position 3; thus [3-isoleucine]vasopressin or [Ile3]vasopressin.
[vaso, pressin + oxytocin]
