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]

vasotocin

the normal antidiuretic hormone in birds. One of the hormones released by the avian posterior pituitary gland. Called also arginine vasotocin, AVT. Is also active in stimulating uterine contraction.
